It's been a few weeks after Sendou Aichi return for disappearing. Everyone was happy to have their happy and cheerful blue hair boy back. Especially Kai Toshiki, who is thrill to have Aichi back with them again. Everything is back to normal, or is it?

Kai Toshiki is waiting for his mate, Sendou Aichi at in front of the Sendou residence. After Aichi return, Kai always accompany Aichi to school in order to make sure that the blue boy didn't disappear on them again. Even though Aichi felt annoyed with the pick up but he appreciate it because he know he would do the same thing if someone that he love disappear all a sudden.

After minutes of waiting, Aichi come out of his residence and hurried to Kai position. "Good morning Kai-kun" Aichi greet Kai.

"Good morning Aichi" Kai greet back.

"Kai-kun" Aichi call.

"Yes Aichi?" Kai look at Aichi.

"Is it really necessary to come and get me every morning and afternoon?" Aichi ask.

"Yes and you know why" Kai answer.

"To make sure that I won't disappear on you guys again and I won't. I promise didn't I" Aichi state but Kai only shake his head.

"I'm not taking any chances" Kai say and Aichi admit defeat.

They walk to Miyaji Academy in silent without a sound. After being send, Kai head off to his school before the bell ring. Aichi enter the class and greet his classmate as he walk to his table. After seated, Aichi laid his head on the table and sigh deeply. Both Ishida Naoki and Komui Shingo see that their friend is depress. With that they come to his table and ask him what's wrong. "Aichi, what's up?" Naoki ask.

"What the matter, Sendou-kun?" Shingo ask.

Aichi just sigh before answer his friends question. "It's Kai-kun"

"What's wrong with him? Is he bothering you? If he is, let me know and I give him a lesson" Naoki say and Aichi sweat drop.

"Violence isn't the best answer Naoki-kun" Aichi say and Naoki just shrug.

"Kai-kun isn't bothering. It just" Aichi stop his sentence and sigh.

"Just what, Sendou-kun" Shingo ask.

"He always come and pick me up before and after school. I know why he did it but I feel like it is a bother because of me, he wake up early to come get me and spend his afternoon to come and get me" Aichi explain.

Both Naoki and Shingo look at each other before look at Aichi. "Aichi" Naoki call and Aichi look at his friend.

"Kai Toshiki is doing that beause he care for you" Shingo answer and Naoki nod in agreement.

Before Aichi could answer, Naoki interrupt "He's doing it because he care for you as a friend. Don't think it as a bother since he is worried about you. Beside he spend most of his time to search for you and now you're here. I'm sure he is worried about you".

Aichi wanted to say about the comment but he couldn't because the teacher enter the class. The conversation end there and will continue other time because now it time to study. After school time, Aichi went straight home without Kai because his aunt from England came to visit and have something important to say to them.

As Aichi return home, Aichi begin to talk to himself inside his head.

'I'm sure that Kai-kun going to be furious with me because I went home without him'

'But it's important and Kai-kun say that he going to be late today'

'I hope he won't get angry with me like last time'

Aichi just sigh and enter his home. "I'm back" he say as he enter but what greet him is shouting.

"I can't believe you that you forget your own child" someone yell.

"I didn't do it on purpose. Please Lily tell me where is she?" Sendou Shizuka's voice beg at the person name Lily.

Aichi rush enter the living room where the two people is and he see his Aunt Lily stand in front of his mother with a red face and his mother is on her knee crying. "You forgot your own child and let her raise by strange until today. If I haven't you about her, I'm sure that you will forgot about her for eternity" his aunt shout.

"Please Lily, tell me where she is. I need to see my baby. Please" Shizuka beg.

"You ask me where did you gave your daughter up. Even I don't know where she is. ALL I KNOW IS THAT YOU GAVE HER AWAY FOR AWHILE IN ORDER TO SAVE YOU OTHER CHILD" Lily shout as loud as she can.

Aichi couldn't take it any longer and rush to his mother side. "Okaa-san" Aichi rush to her side.

"Aichi" his mother call him.

"So it appear that your other child is alive" Lily ask.

Shizuka didn't answer but Aichi did. "Aunt Lily, why did are you yelling at okaa-san".

His Aunt Lily just stay quiet and stare coldly at Shizuka and return her stare at Aichi. "Aichi" his aunt caught his attention for awhile before continue, "I want to ask you something"

"What is it" Aichi ask.

"Did you know that you have a twin" she say and Aichi shock.

"A what" Aichi ask.

"A twin" Lily repeat.

Aichi stay silent after knowing the fact that he has a twin. His aunt just laugh in bitter. "I am right, aren't I Shizuka. Your own son didn't know that he has a twin sister" Lily say as she stare at Shizuka who is crying.

"Aichi" she call her nephew and continue her sentence, "Your mother gave birth to twin as in you and another child. At the time you and your twin were born, you were terribly sick that you couldn't be with your twins. Every time you with your twins, you get sicker and sicker until your parent thought that it would be fine to separate you two for awhile" she tell Aichi about him and his twin.

"But" Aichi look at his Aunt as she continue, "It appear that your mother forgotten about your twin and now your twin is no where to be found and is raise by a stranger".

Aichi just stand their dumbfound beside his mother while his mother cry none stop. "Please Lily, tell me where she is" Shizuka beg again but Lily stare at her with her cold eyes.

"I don't know, Shizuka. You gave her to you friend, Minako, who disappear years ago" Aunt Lily say before she grab her bag and wanted to left.

Before she did, Lily stare at her sister-in-law again and say something to her. "Shizuka" she call and Shizuka look at her. "I'm going to make a report for your child and if she is found, I want you to take care of her before I take her under my care" she say and Shizuka nod in agreement.

With that Lily leave the Sendou Residence and leave two people in a dumbfound state. Minutes later, Sendou Emi return from school. She see her mother and brother on the floor. "Okaa-san, Aichi, what's wrong? Where Aunt Lily" she ask but Shizuka only answer with crying and Aichi just stay silent but in his head there all kind of question came and one of them is 'I have a twin?'
