Suga accidentally drops one of his love letters that he on accident forgot to take it out of his bag and so happens to be the last person he wanted to read it and finds it on their gym floors. Oikawa had read through the love letter, thinking it was for someone else's but is really for him and now he wants to find out who wrote this love letter.

Chapter 1: Secret Lover?

Chapter Text

“Congratulations Oikawa Tooru. You deserve this award truly.” 

 

“Thank you.” 

 

A pair of hazel eyes stared down at the courts along with other spectators as he was focused on the boy who received the award. The setter and captain in Kitagawa Daiichi, Oikawa Tooru had received the Best Setter Award in their prefecture. Suga has seen his matches and that displayed everything that the person needed to get the award. That the award had meant a lot to Oikawa after losing to Shiratorizawa Junior High but still that smile didn’t seem like he was happy and Suga could tell.

 

Oikawa had tears flooding down his face and a runny nose, pointing to a first year and declaring something that Suga couldn’t hear. The first year passed him a tissue and the third year snatched the tissue out his hand and blew his nose. 

 

Suga had felt something that made his heart beat slightly quicker from looking at Oikawa. He didn’t know the feeling but he could feel his cheeks going redder. He placed a hand where his heart was and lightly clenched it. 

 

“Sugawara-san! Are you coming? The final match is over!” His friend called over as Suga snapped out his thoughts.

 

“Right! I’m coming! Don’t leave without me!” Suga got one last glance of the brunette and then ran off towards his friend. 

 

Ever since that first feeling that Suga had gotten, it hasn’t stopped when he started high school and when Aoba Johsai were at the preliminaries and Oikawa would be there. His heart would go faster when he looks at him along with a tendency to blush as well. 

 

He began to write letters, not for Oikawa to read but for Suga to keep it like a diary. He knew he wouldn’t have a chance with the setter, not when he’s not even up to par with his skills. Every time he would Oikawa or find him a volleyball magazine, he’d find writing letters a way to control his feelings if he wrote it out like a story or a small journal. 

 

None of his teammates know about it, not even Suga’s bestest friends, Daichi and Asahi, that have been by his side ever since they began high school. 

 

“-Wara-san... Sugawara…-san! Sugawara-san!” 

 

Suga flinched hearing his name, “Sorry Yamaguchi… Is there something wrong?” 

 

“You seemed a little out of it, are you ok?” The green haired first year asked, concerned.

 

He shook his head and assured him that everything’s ok, “Just a little disappointed that Kageyama gets to play this whole match…” 

 

“Oh…” 

 

Suga pursed his lips, staring at the match that was playing against Aoba Johsai at the moment. They wanted Kageyama to be playing the starting setter position rather than him. It surprised Suga when he first heard the request but he told himself that it would sound selfish if he didn’t let Kageyama play since he was a first year who’s gone through a lot.

 

At first, Hinata was screwing up the first set and Aoba Johsai got the first set but after Kageyama cooled him down, they could do their spikes and Hinata could be the decoy that they needed. When Karasuno won the second set, Aoba Johsai were surprised by the change of Karasuno and they had to step up their game. 

 

Just when things were comfortable for the third set it was soon interrupted. Suga couldn’t believe his eyes, he never expected to see none other than Oikawa Tooru inside the gym talking to the coach. He didn’t hear what exactly happened to Oikawa but he overheard that he was the one who decided to make Kageyama play this match and he was injured or something.

 

“Sugawara-san… Who’s the person there?” Yamaguchi asked, whispering to him.

 

Suga clenched his hands and bit his bottom lip, “He’s the captain and starting setter of Aoba Johsai, Oikawa Tooru.” 

 

“So that means that setter that they’ve been using is not the starting one!?” 

 

“I’m afraid not… This might be an obstacle now…” Suga replied back, wondering out of all the times he could show up but it had to be the time when they were going to finish off Aoba Johsai in the third set. 

 

Suga looked over to Kageyama, he didn’t look like he was panicking and that relieved him a little but that did not change the fact he was still concerned if Kageyama would change when Oikawa came into the match. 

 

“Do you think we’re going to be ok?” Yamaguchi asked, worried for the team. 

 

“Of course, our team isn’t weak, we’ll be just fine…” Suga replied back but even the tone of his voice did not convince Yamaguchi that the team was going to be fine. 

 

Oikawa was put into the match after Karasuno was on match point. He was the one serving and Suga knew exactly how dangerous his serves were back in middle school but they definitely are more dangerous now. Suga could see the tension on Karasuno’s side now, Kageyama was feeling a little nervous too.

 

Oikawa’s first two serves were aimed at Tsukishima after figuring out that he and Hinata were their weak receivers. Suga’s heart beated faster, not knowing if it was because of Oikawa or it was that he was building up points for their team and blocking Karasuno from the win. 

 

Daichi changed their formation as he was standing in the middle of their side. After all the changes, Oikawa had done a serve that was more of accuracy than power, Tsukishima was able to receive it but the ball was going over the net.

 

“Oh? He received it? Good for him but this is our chance ball now…” Oikawa smirked, receiving the ball to their setter. 

 

Suga felt out of breath even though he wasn’t on court, Hinata managed to block the ball with one hand which was lucky. It was time for their counter attack now, Hinata landed on his feet, quickly sprinting over to the other side of the court. Kageyama tossed the ball over to their middle blocker and he spiked the ball right beside Oikawa but he wasn’t fast enough to receive the ball. 

 

The match was over, 2 to 1 with Karasuno winning against one of the top 4 high schools in Miyagi Prefecture. Suga took a deep breath of relief that they had won, the team grouped up for some words from Takeda. 

 

As Karasuno was finishing and packing their stuff up, Daichi approached Suga with a small frown on his face, “Suga.” 

 

“Hm? What’s up, Daichi?” He asked back, grabbing his bag and put the strap over his head. 

 

“Are you ok with Kageyama taking your spot for this match?” 

 

Suga raised a brow but soon grinned, “No, the match is over, Daichi. Why would I still be holding grudges?” 

 

Daichi tensed up and nervously laughed afterwards, “Nevermind, forget I said anything.” 

 

“Besides, I wanted to change Kageyama and prove to others that he’s not the same. So I’m willing to do anything, even if it risks my position but I’ll be fighting back. He might be a genius but I have more experience than him,” Suga replied back, standing determinedly, he was not letting a first year go by him that easily and take the position.

 

Daichi sighed and muttered to himself, “At least you’re not going to leave the team because of it” 

 

“What was that, Daichi?” 

 

“Ah! Nothing! We should start heading back to Karasun now!” He replied back, changing the subject and walked over to Takeda. 

 

Suga blinked a few times but stared over to the other team with a small frown on his face. Maybe they got lucky that Oikawa wasn’t on the court the whole time, if he came in the second set they might’ve lost to them. His eyes wandered over to their captain, his cheeks glow a light pink. He widened his eyes realising what he was doing and slapped his cheeks, looking away.

 

‘Staring at someone is weird, Koushi! Keep it together!’ He told himself and walked towards Daichi and Takeda. 

 

When Karasuno had left the campus to return back to their school, Seijoh was packing up the equipment after practices soon later. Something changes the captain of Seijoh’s eyes and finds a pale pink envelope on the ground and picks it up off the ground. It didn’t look like it slipped under the gym doors but more like it fell out of someone’s bag or something. 

 

Oikawa raised a brow, curiously turning the envelope over as there was a small red heart sticker sealing the envelope. This isn’t the first time that Oikawa’s seen a love letter but he was not sure who the letter could be for since there was no name on it or anything.

 

‘Since there’s no name, there’s nothing to lose if I just read some of it,’ he told himself in his head, gently opening the envelope and took out the piece of paper that had been folded three times.  

 

Oikawa opened it up and the handwriting was nicely printed. It wasn’t familiar to him so he guessed it wasn’t one of his frequent fans that kept writing him love letters even though he had rejected them. 

 

Why must you be so unapproachable sometimes?

 

Why must you play with my feelings just when I look at you?

 

You’re always the centre of attention.

 

You have many fans that I can’t compete with because I’m out of your league. 

 

Why must I be in love with you out of all people?

 

Out of everyone in the world, why are you the only one who makes my heart pound like this?

 

All I do is gaze at your beauty and I can’t help but be mesmerised by you. 

 

Why do you make me out of breath whenever I see you?

 

But you don’t know me.

 

Am I weird for liking you?

 

Why must I love you, Oikawa Tooru?

 

“Trashykawa! What the hell do you think taking a break while the rest of us are tidying up?! You haven’t done anything!” Iwaizumi growled across the court, glaring at the brunette.

 

 “Haha… Sorry Iwa-chan!” Oikawa quickly put the letter away in his pocket and rushed over to help out.
