The time period will be for season 1. So season 2 doesn't matter in this fic.

Sorry if Nagisa seems OOC but like I said this fic is going just by season 1 and season 2 is where they get into Nagisa's character so this is my take on his way of thinking. If you don't like it please tell me why and I'll take it into consideration when I write the next chapter or just don't read the fic.

It was his own fault.

He should have just minded his own business. He shouldn't have agreed with Gou's idea to come to Haruka's house unannounced for a meeting. They shouldn't have just assumed that Haru was doing nothing, that he was just in the bath or something. He has known Haru for years, he knows that Haru is actually keen on having his alone time. He should have known better.

Running ahead from the others, Nagisa arrived of breath, Nagisa hunched over, panting, thought to himself why the hell he thought running up stairs were a good idea? Looking back down the stairs, he didn't see Rei or Gou behind him so he leaned against the wooden fence to wait for them. He figured he should wait since knowing them, one will scold him for leaving them behind and he would rather they did that outside than in front of Haruka.

'It's not my fault they're so slow. Rei-chan's the runner of the group, if anything he should have been able to catch up!'

Nagisa groaned out in annoyance. At Rei or himself he wasn't sure. He knew that he was acting childish since he knew he was in the wrong. If Rei had ran with him, Gou wouldn't have been able to keep up and leaving her alone wasn't an option. Rei did the right call in not going along with Nagisa's game. Still it bothered him that Rei didn't even attempt to catch him to make him stop. What if something happened to him while he was ahead? A little attention was all he wanted.

Kicking the dirt on the stone floor wasn't entertaining him anymore so he pushed himself of the fence and looked down towards Makoto's house. He thought about going down there to get Makoto and use him to invite himself in Haruka's house. Makoto doesn't need an invitation to go to his 'second home' and being with Makoto extended that access to him. It was the perfect plan.
He walked down the stair only to stop and walk back up again.

'Mako-chan is sick. Duh.'

Nagisa didn't know what to do. He could always just go and be entertained by the Tachibana twins but as much fun that would be, it would also be tiresome. The twins were a lot to handle, even for him.

'Wait. If Mako-chan is sick, wouldn't Haru-chan go and be with him?'

Was Haruka even home? Looking towards the house, he saw none of the lights on and even though it was still daytime and maybe an hour until sundown, if Haru was doing homework or something in his room, then the light would be on. Nagisa walked up the walkway and was about to just walk to the backdoor, when he saw the front door was slightly open. He slid open the door all the way and let himself in. Haru's name was at the tip of his tongue when he stopped himself. The atmosphere of the house felt tense to Nagisa. He didn't understand it. It felt as if he was home and walked onto his parents arguing about him. He felt a bead of sweat run down his temple. The tension was palpable and felt suffocating.
He took a few steps until he was in front of the living room door. Raising a shaking hand, he held onto the door handle and pulled. No one was in there.

'So much for ripping off like a bandage.'

He couldn't hear anything in the kitchen so he just slid the door close.
This would definitely be easier if he would just call out Haruka's name but it felt wrong. Haruka would find him here and question him on why he was here. He didn't know why that bothered him so much, it just did.
Turning towards the entrance, he decided that it would be best to just leave and wait outside. Fifthteen minutes only past from the time he first arrived and Rei and Gou should be here soon. As he opened the door he heard it. He was certain that he could hear a muffled noise coming from upstairs.
Nagisa jumped as he heard a loud slap echo in the house. The slaps kept coming one after another. Some fast and others slow. He did what any other person would do in this situation.

He ran out the house and just sat on the stairs.

Nagisa is adventurous and bold, but that doesn't mean he's completely courageous. Clearly, Haruka was home and Nagisa's odd feelings were justified. Either someone was doing something to Haruka or Haruka was doing something to someone. Ugh, mouthful.
Nagisa's buried his head into his lap and tried to think of what to do. Either Haruka was getting hurt or was hurting someone and someone had stop it. He just didn't want that someone to be him. What if he barged in and the culprit turned their attention to him. But Haruka is his friend. He couldn't just stand by and do nothing.
Nagisa was so wrapped up in his thoughts that he barely heard the voices that we're getting louder by the minute.
Looking up, Nagisa sees Rei and Gou walking around the corner and making their way up the staircase.

"He's not home."

The words were out of his mouth before he could stop them. Why? Why! Why did he just lie? He could have had help from 2 other people yet he chose to keep it to himself. Nagisa internally winced at his own dumb thoughts. He already knew the answers so why bother questioning it.
They all care about Haruka and worry for him because of his quiet personality and strange/volatile relationship with Rin. Although Haruka is taciturn and reserved, he's the glue that kept their little group together. He is loved and wanted by everyone that meets him.
And honestly, Nagisa's jealous.
Not jealous of the attention that Haruka gets, but in the fact that everyone wants to be closer to him. It's so selfish of him. Makoto is the only exception to this jealousy, even Haruka being with Rin made him jealous. Makoto and Haruka's relationship is something that Nagisa would never mess with; their bond is unbreakable.
Nagisa stood up and went down the steps towards the pair. As he stood in front of them, he knew what he would do, he had made his decision.

Convincing Gou and Rei to leave was difficult.

His simple answer of "I checked the house, no one was home," wasn't enough for them. Rei had suggested in just waiting a bit to see if Haruka would return. Gou agreed but Nagisa had just shrugged.

"I've been here for," pulled out his phone to check the time "... 20ish minutes already, waiting for both of you. So I doubt he'll be back anytime soon."

Rei obviously understood the logic behind Nagisa's words but Gou argued and insisted in waiting for Haruka to return.

Nagisa was this close to yelling at Gou. What was the point of this stupid meeting anyway? Today club activities were cancelled and today should have been a day-off but no, Gou insisted that we go to Haruka's house for a meeting. Who was she kidding. She just wanted to come here to be with her precious Haruka-senpai and needed an excuse. Seriously, do the Matsuoka family all have yearnings for the impassive boy?

Gou finally gave up when the sky started to change from blue to a light orange.

"My mom's probably wondering where I am… It seems like we came here for nothing."

Did it not occur to her or for the matter of fact, Rei that they could have visited their sick friend, who lived a house down the hill. Nagisa scowled at the recent memory. Why wasn't his word enough for them? Did they really think he would lie to them? I mean he did. But that wasn't the point. He needed Gou and Rei to leave so he could set his plan into action. So he was grateful that they hadn't thought of visiting Makoto. He needed Makoto for his plan.

After telling Rei that he was going to visit the Tachibana household and guilted him into not accompanying him by telling him that he needed to walk Gou, he walked over to Makoto's house. He rang the doorbell and waited. He could hear the twins trying to get to the door. But at the end the one who opened was Mama-Tachibana herself.

"Nagisa-kun! What a pleasant surprise!"

"Good Evening ! How's Mako-chan?"

"Um, I'm not sure what you mean by that? Doesn't he have swim practice with you today?"

Shit. What?

"Club activities were cancelled today. Mako-chan said that he wasn't feeling well today so I thought he would have gone home right after school."

"Oh! Well he hasn't been home, knowing him he's probably at Haruka-chan's house making sure he does his homework or something. Ah wait! Today is Monday! He probably went to buy groceries with Haru-chan. You know that boy needs to eat better! If it weren't for this family, he probably would eat nothing but Mackerel, but that was most likely earlier today. Nevermind, he's probably at Haru-chan's house."

"Ok! Thank you."

'So Mako-chan lied to us? Lied to his mother? Wow I never would have thought'

Nagisa wasn't sure what to do at this point. Right now he was sitting on one of the stairs staring at his phone. He tried calling Makoto but he didn't answer. He stared at the group chat that Makoto had made, stating that he wouldn't be in school today because he was feeling under the weather.

Makoto skipping school isn't something he would normally do. Haruka skipping today made more sense seeing that he usually doesn't go if Makoto doesn't.

Nagisa's eyes widen in alarm.

'The slaps. Were… were they fighting?'

That bond that Nagisa respected, the bond that he longed to be apart of, was it endanger?

Nagisa stood up and turn towards Haruka's house. He had to be sure. He needed to know they was safe.

So he ran.
