A/N: A birthday fic I wrote in the name of AsuCaga. I apologize if I'm posting this after their birthday. It's just that, our internet was cut for some stupid reason. So I only got to access the net just now.

This was supposed to be a one-shot but I realized that it got too long, so I decided to separate it into four parts! :) Plus, I'm actually not yet done with the fourth part so… Haha.

Notes before reading this fic:

- This is set 2 years after the second bloody valentine war (CE 75)

- The Seiran family did not hide Djibril, therefore they weren't put into custody.

- Yuuna did not die (unfortunately).

- Athrun Zala is in Orb, and an admiral at that.

Disclaimer: I do not own Gundam Seed/Destiny.

May 18. How he looked forward for this day to finally come!

Each year, during the 18th day of May, Cagalli had a mandatory day-off. Although she didn't really want to leave her duties as the representative of Orb even just for a day, it was the parliament's request. They at least want her to relax and take a break during her birthday, since she worked almost everyday, even during the holidays.

He planned a birthday surprise for her this year. Last year, they had dinner with Kira and Lacus. But this year, he wanted Cagalli to spend it with all the people that became part of her life, but rarely get to see because of her tight schedule. Kira would be there of course because it was his birthday. Lacus, Reverend Malchio and the kids, Archangel crew, Athha household, some of the Morgenroete team, Dessert Dawn, her friends from school were all invited. Even the people from PLANT, Yzak, Dearka, Shinn, Lunamaria and Meyrin were invited to celebrate Cagalli's birthday.

It was a good thing that he planned the surprise to happen during dinnertime. He had the chance to spend the day with Cagalli like a normal couple. Cagalli told him that there was a new amusement park in Onogoro Island that she wanted to go to, but never had the time. It was "Haro Land", made in tribute of the cute robots that always trailed behind Lacus Clyne, a very influential figure. Athrun too find it interesting so he bought the tickets ahead of time and was really excited to go and have their date. He also had his duties as the admiral of Orb so it was such a luxury to be able to be with her for the whole day.

Kira and Lacus, busy themselves with their obligations back in PLANT, were too kind to help him out with the preparations for the surprise party. The decorations and checking if everything on his checklist was complete. They told him that they weren't really going to do much since Athrun pretty much took care of everything and that Athrun should go and enjoy his date with Cagalli. They enlisted the help of their other friends so that things would go smoothly.

Athrun told them to come to the Athha mansion once he fetched Cagalli. After they leave, they were supposed to bring in everything that they needed for the party to be perfect.

Looking at the mirror for the last time, he was confident that they wouldn't be noticed this time. He had on a dark tint of shades so that people won't be able to see their eyes and brought a cap to disguise himself further. It wouldn't be weird for them to be wearing those at an amusement park anyway.

He remembered her birthday last year when they visited Ocean Park. They looked really suspicious with their shades and caps. Since the tint of the sunglasses was too dark, Cagalli removed hers complaining that she couldn't appreciate the fish that much. As a consequence, people immediately noticed that it was their Princess and wanted to get her autograph and have their picture taken with her. Before they knew it, they were dashing and hiding everywhere and ended up having a simple dinner with Kira and Lacus at the orphanage.

Chuckling at that funny adventure last year, he finally went out of his flat and went to his car. He checked his pockets when he entered the car.

Phone? Check. Wallet? Check. Handkerchief? Check. Keys? Check. Tickets? They were with Cagalli. Check.

All right, he had everything that he needed. His clock read 9:45am. They agreed to meet at 10am and Cagalli's place was only a five-minute drive from where his flat was. He'll be there on time. He texted her to that he was headed to her house before starting up the car and driving for the Athha mansion.

In no time, he was already in the Athha mansion. He parked his car near Cagalli's other cars. As he walked his way to the door to ring the doorbell, he noticed something that was odd. There was an unfamiliar car parked in front of the door. Who would visit her on such a day?

As he got closer to the door, he kept examining the parked car. When he finally saw a seal that was on the plate number, his eyes were now wide open.

It was none other than the Seiran family seal.

"Damn that bastard Yuuna Roma Seiran!" He cursed under his breath. "Trying to ruin our plans for today."

He seriously wanted to barge into the mansion and give that purple-headed freak a piece of his mind. No wait, a piece of his fist on that bastard's face. Whenever he got the chance to spend time with Cagalli, that dingo would beat him to it and would hog Cagalli until she has to get back to work.

Although he was indubitably ecstatic that their wedding didn't push through two years ago, all thanks to his best friend for kidnapping his princess, Seiran was still such a pest. Right after the second bloody valentine war, he broadcasted to the public that the incident of kidnapping Orb's princess did not mean that they were breaking off the engagement. Rather, they were only waiting for the right time to get married, as Cagalli was still young.

Athrun and Cagalli were really surprised that he had made that announcement when in truth, there was no longer a marriage that would happen between them, especially when the prick told the Orb soldiers that the pilot of Strike Rouge wasn't Cagalli and when he ordered them to shoot her down. The couple had the same sentiment at that moment, to shoot Yuuna Roma Seiran, down.

Since Seiran made the announcement to the citizens of Orb, the parliament advised Cagalli to just go with it for now, even if it appalled her. Cagalli comforted him, saying that she will soon announce to the public that they are breaking off the engagement. But still, Yuuna had the advantage of freely being with Cagalli whenever he wanted while he had to meet Cagalli in secret. It burned him to be in that kind of situation.

Yuuna also knew that the two of them were secretly together. That was why he was doing everything that he could to take Cagalli away from him. Since now he came out as Athrun Zala, not Alex Dino, he was also eligible to become Cagalli's fiancé. But he had the trump card of being her current fiancé. This was a war between the both of them.

But Athrun Zala wasn't going to let him win this time. Any other day was fine, just not today.

He was about to enter the door to confront Yuuna. Oh he was ready to bicker with that purple weirdo if he had to, but was stopped by Mana.

"Athrun-sama!" Mana tried to calm him down, preventing him from entering the door. "You musn't!"

"Why not Mana-san?" Athrun contained all his irritation with Seiran. "He's at it again. Cagalli specifically told him that she wasn't free today."

"Calm down, Athrun-sama. You see, hime-sama-" Mana tried to explain, but they heard voices that were from inside that was getting louder. Mana dragged Athrun to hide with her in one of the bushes near the door.

"I keep on telling you Yuuna. I have other plans today!" Cagalli was arguing with the Yuuna who also went out of the door. She was currently in the process of pushing him to his car.

"You have to celebrate your birthday with me! I already told my family and they're already expecting you to have lunch with us." He told her while grabbing a hold of her arm and motioning her to enter his car. Athrun was clenching his teeth. How dare that bastard make plans without even consulting her?!

"But really I can't go!" Cagalli wriggled out of his grasp and managed to break free. She dropped her bag though, causing the amusement park tickets to be visible to Yuuna's line of sight.

Cagalli had a shocked expression on her face; Yuuna smirked, which irked the two that were lurking in the bush even more.

"Cagalli my honey," Yuuna started to speak with the most annoying voice. "You didn't tell me that you wanted to go to the amusement park." He picked up the tickets that Cagalli tried to get from him but hid it from her reach. "You should have told me! That's why you're wearing those kind of clothes." He said while examining Cagalli's casual outfit. She was wearing a white peplum top and jeans.

"Yeah, so give it back!" She tried with all her might to get the tickets from him but he was just too tall.

"Nonsense honey!" Yuuna refused to return the tickets to her, even if he knew that the other ticket was supposed to be for Athrun. "We'll do as you wish, we'll spent the day at the amusement park!"

"Wha-" She wasn't able to finish was she was about to say because Yuuna forcefully shoved her inside the car, he also went inside and quickly shut the door.

Realizing that Cagalli was being kidnapped, Athrun stood up from where they were hiding even if Mana tried to stop him and tried to go and rescue Cagalli from the moron. But the car was already on its way out of the Athha mansion, driving at a speed that wasn't supposed to be allowed on that kind of location.

"Yuuna! You bastard!" Athrun was helplessly screaming as he tried to chase the car. "Come back here!" Even if he was a coordinator, he was still running after a car that was speeding away from the Athha mansion.

He kept on running after the car until it became smaller every second. There was no use; it was impossible for him to save Cagalli if he just ran like this.

He paused for a moment to catch his breath. He rested his hands on his knees and tried to recompose himself. He needed to chase them. Then he realized that he should have just used his car to catch up to them, and he would have done so in no time. So fine, coordinators make stupid decisions on impulse too.

Another car was headed to the Athha mansion while he stood there motionless and panted. It stopped to where he was and the windows were rolled down. Athrun was surprised to find that it was Kira and Lacus.

"Yo Athrun! I saw a car headed out, and I assumed that it was Cagalli, so we're here to prepare for the party." Kira, who was driving, greeted him cheerfully, unable to notice that something was clearly very wrong here. "You didn't tell me that Cagalli would go ahead without you. I thought that you told us that we would set up ourselves?"

"But if you're here…" Lacus seemed to process what happened based on seeing a car that was similar to what the Seirans used on their fail wedding day two years ago, Athrun breathing heavily, and the tacit rivalry between Athrun and Yuuna.

Kira was now laughing. "Yuuna did it again, didn't he?"

He pilot of the Infinite Justice could only nod in defeat.

It was very frustrating. Every single time, Yuuna has been getting in the way. They were successful enough to escape from his sight last year. It looks like he has really been wary this year. He had been too careless for thinking that the pesky Yuuna would let them do as they please.

Damn it.

Athrun then realized that it was time to counterattack. He had been enduring this situation for four years already, and he was on the edge. That egoistic purple brat was going down. He couldn't take this anymore, especially when he was messing with him on Cagalli's birthday. This might be the only day he gets to have a date with her this year and that good-for-nothing is trying to ruin it.

This means war.

"Get in." Kira cut his train of thoughts and tried to calm his best friend down. He knew that Athrun was really in a bad mood, but he couldn't blame him. Truth be told, he too was annoyed with Yuuna. Even if he was Cagalli's brother, Yuuna didn't like it that much when Cagalli always visited them in the orphanage. 'It's not good for you to be interacting much with coordinators, especially that you're a natural.' He says. They were siblings for crying out loud!

Athrun opened the door of Kira's car and sat on the back seat. "Lacus," he called out to his former fiancée.

"Yes Athrun?" Lacus turned to him, giving him an understanding and encouraging smile.

"Can you handle the preparations without Kira? Aunt Via and the others are there to help anyway." Athrun told her in a very serious voice.

"Yes I can handle that." She replied, sensing what he was planning to do something with Kira's help. "Don't you worry, I'll give my best."

Kira laughed again. "It'll be a surprise birthday party for me and Cagalli instead since I'm not going to be there too."

"Thank you Lacus." Athrun was grateful that she understood for the need to pull out Kira from the: 'Operation: Decorate Cagalli's house before they come back'.

"Athrun…" Kira knew what Athrun was planning to do. This was one of those moments wherein Athrun didn't really need to tell him what was oh his mind because he comprehended perfectly. In the past two wars when they fought together, they always had these moments.

"Kira…" Athrun responded. As if they were communicating their thoughts telepathically.

"Yeah let's bring back Cagalli." Kira gave his best friend a thumbs-up.

"By the way, happy birthday Kira." Athrun greeted him as well. "Are you sure you're okay with this?"

"Of course I am! I got to celebrate my birthday three times this week. Plus, when we get back to PLANT, my team wants to celebrate with me as well. Meanwhile, Cagalli only has this one chance. That's why we have to get her back."

So what if Kira Yamato was now a part of ZAFT and Athrun Zala was a part of Orb's Military? Freedom and Justice will always have that imperishable bond as allies in times like these.

-o0o-

"Were you able to locate them?" Kira walked to Athrun and gave him a drink. He sat down the bench where Athrun was sitting. They followed Cagalli and Yuuna to the amusement park. But since the amusement park was so big, they had no idea where they could possibly be.

Athrun took a sip from the soda and shook his head. "Not yet." He was actually wearing binoculars to help him search his blonde girlfriend, but it was no use. He could not see her.

"Why don't you make a call?" Kira asked him. "It might help."

Athrun put the drink down and nodded. "Good idea." He got his phone from his pocket and started to dial Cagalli's number.

It was ringing. Thank goodness the freak didn't try to confiscate her phone or anything.

He wanted to jump for joy when Cagalli finally answered the phone. "Athrun!" It seemed like she was very relieved. Her voice was like from someone who was kidnapped and was trying her best to hide it from the person who abducted her. She also wanted to get away from Yuuna, for sure.

"Cagalli," Athrun tried to contain his excitement and ask her quickly. "Did you go to the amusement park?"

"We did, even though I refused to." She said. "He even used your ticket! Argh, I'm so pissed-"

"Where are you?" Athrun cut her off. He didn't want to do that, but he had to know where she was so that he could get her immediately.

"We're in aaah!" He heard Cagalli scream. "Give that back! Yuuna!"

Athrun gritted his teeth. He could only guess that the kidnapper finally noticed her taking a call and snatched her phone away from her before she could tell him where they were.

He could still hear them talking. "Now, now, my honey. It's your birthday isn't it? You shouldn't be taking calls."

"That's a very important call!" Cagalli retorted. "Now give that back!"

There was a few seconds of silence and finally his purple rival began to speak. "What is this important thing that this incompetent admiral could not wait to tell you until tomorrow? Geez."

Athrun was getting very provoked. How dare he call him incompetent? If there were someone that was incompetent, it would be none other than him! Bastard Seiran! He's so stupid that he isn't even supposed to be in the parliament!

"Oy Mister Admiral." He could hear Yuuna finally taking to him. "We're having a date today, so don't disturb my honey today. That's an order." With that, the line was cut. He didn't even have time to respond because Yuuna already hang up.

"Damn you Seiran!" Athrun tried to call Cagalli again but the line could not be reached. That twit must have turned off her phone and confiscated it from her. He was dialing again and again, but it was futile.

It was a good thing that Kira was there so at least there was someone that was thinking rationally. "Athrun…" He called out to him. "There's no use."

He was right. There was nothing that he can do. He was only draining his phone's battery his energy. Athrun took a very deep breath and put the phone back in his pocket. "You're right. Sorry about that." He took a sip from the soda again to calm him further.

"It's alright." Kira reassured him. "We can still find them."

"Yeah." He nodded, recomposing himself. "I don't know if I'm correct, but I heard the sound of a rollercoaster in the background."

Kira opened the map that he was holding. "It says here that the rollercoaster is right ahead. Most probably, we'll find them nearby."

"Let's go."

-o0o-

"They really are here!" Kira exclaimed while hiding at a post, dragging Athrun to hide along with him. They went to the area where the sound of the roller coaster could be heard, and there they saw Cagalli and Yuuna, by the game booths.

"Let me borrow that." Athrun was handed the binoculars and he put them close to his eyes. True enough, there was Cagalli and Yuuna, approximately thirty meters away from them. The look on Cagalli's face immediately told him that she wasn't very amused being with Yuuna, which lighten him up. He gave back the binoculars to his best friend and was about to approach the both of them.

His plan was simple really. It was so strike Yuuna in the face, making him unconscious, rescue Cagalli and finally get to spend the day with her.

He was about to execute his plan, but Kira pulled him back. "Wait Athrun!"

First it was Mana that stopped him, now it was Kira. "What is it?" Maybe Kira wanted to first devise a plan?

"You shouldn't do whatever it is that you're thinking right now." His best friend advised him.

"Why not?"

"Look closer." Kira put the binoculars in his hands.

He did what he was told, and realized that there was something that would make his plan unsuccessful.

Cagalli's left hand was cuffed to Yuuna's right hand.

Rage was starting to take over him yet again. Of course! That was a desperate attempt of the jerk to make sure that Cagalli wouldn't escape. He was really treating his princess like a prisoner, on the day that she was supposed to be free to do what she wanted to do!

"If you try and punch the daylights out of him, it would surely be noticed by a lot of people. Plus you might also hurt Cagalli in the process since they're chained to each other." He explained.

Athrun realized that Kira was right. It seemed like Yuuna wasn't a fool with regards to how he could separate him and Cagalli.

"Let's follow them!" Kira suggested. "We might think of a way to rescue Cagalli, and at the same time, get back at Yuuna!"
