Angst, cheating, stuff like that.
*********

"Iwazumi! Let me block you!" You yelled as you bursted through the gym doors, late to practice. "(L/N), you're late, again." "It's not my fault god decided to have a day to himself!" You heard Hanamaki and Matsukawa laughing, cackling to yourself at your dirty joke. "Snow! Say it with me, snow!" Iwazumi yelled at you, "God's cum." "You-" You ignored him as you stretched, "So, 'm blocking you or no?" He stopped lecturing you, Hanamaki and Matsukawa in the background laughing, "Sure, get over here." "Fuck yeah, boy!" You low-fived the two dorks as you stood in front of Iwazumi, Tōru with him.

Tōru set the ball to Iwazumi, who ran up to it and spiked it down, the sound of the ball hitting off your skin filled your ears as the feeling fueled the adrenaline. You had a wild smile on your face as you landed, bringing your hands to your hips, "Hell yeah! Look at these guns!" You flexed, kissing your biceps as you heard Hanamaki and Matsukawa snickering, "Tōru, what are you doing over there? Come join the winners, baby!" You put your hands behind your head, getting a chuckle out of Iwazumi as the other two held on to each other, "Well, if you insist," He went under the net and pulled you by the waist, "Ooh, we gettin' romantic," You wiggled your eyebrows at him, "Ew! Stop being sappy!"

Hanamaki stuck his tongue out as Matsukawa laughed, "You're just jealous I get more action than you!" Tōru yelled as you laughed into his shoulder, "Shut up and practice!"

"Hey, Iwazumi?" You two were hanging out in his room, Tōru would usually join you but he said he wanted extra practice. "Yeah?" He looked up from the magazine in his lap, "Has... has Tōru seem distant to you?" You asked from the floor, staring at his ceiling. "No, why?" He sounded skeptical as he closed the magazine, "He doesn't hang out with me as much anymore, and-and he hasn't even said 'I love you' in almost two months- even when I say it he just says okay or something like that and leaves it alone and it's-" You started crying as you talked, speech speeding up as you tried to gather your thought. "I'm sorry, I-I shouldn't be laying this on you, it's just-"

He got up from the bed, "Hey, it's okay. We're friends, so it's fine that you're telling me this." He sat down beside you, "Maybe he's stressed for the upcoming games, god knows the idiot would do anything to make it to number one," You cracked a smile, "Y-yeah, you're right. I'm probably just over reacting. Thanks, Iwazumi." You hugged him, he hugged back.

You were walking through the halls on your way to class, you just said goodbye to the other third year minus Tōru, who left earlier for whatever reason he didn't bother explaining to you. you turned the corner, almost dropping your phone as you saw Tōru pining a girl to the wall, making out in the hallway. You quickly walked backwards, hoping you weren't seen as you stood still, pressing yourself against the wall. Your heart was pounding as you stood there, "What about your boyfriend?" Oh, that bitch. "It's fine, he doesn't expect a thing." That fucking bitch. Your vision blurred as you ran down the hallway, stumbling into Matsukawa and almost sending you both into the ground if he didn't have fast reactions.

"Hey- (L/N)? What's wrong?" He quickly pulled you into the bathroom, "Hey, hey, what's wrong?" He held your shoulder before you hugged him, tugging him as close to your body as you could. He hugged back, confused and concerned on what was happening as you cried into his shoulder, both embarrassed but to sad to care. "H-he-" You hiccuped, "He fuckin-" You couldn't finish the sentence as your body convulsed, crying harder. You both stood there for awhile (you're pretty sure Matsukawa scared someone off at some point) before you pulled back, "I got snot on your shirt, sorry." You mumbled as you wiped your eyes, "It's cool, it'll come off. But what was that?"

Your vision started to blur again before you felt hatred, "Wow, breath. In, out. In, and out." You followed his instructions, calming down enough to speak. "What were you doing in the hallway?" "Not important. What has you so upset?" You took a deep breath, "I saw Tōru... fuckin' eating a girls face!" You felt the hatred again, "He what?" You could tell he was trying to keep it under control, "He was face fuckin' a girl in the hallways, and-and she fuckin' asked about me! And you know what he said? 'Oh, it's fine!' It's fine he says!" The tears were back, streaming down your face. Matsukawa put his hands on your shoulders, "Are you going to tell them?"

You scoffed before remembering that you were all practically best friends. You could ruin this man's reputation. "Yeah, I think I will." You sniffed, "But first, you need a lot of tissues and some time to wash up." Matsukawa took off his jacket, "And you're going in the bag," He mumbled to himself as he folded it up. You chuckled.

After your interaction with Matsukawa (and him asking if you'll be alright by yourself- the gentleman) you spent a little longer in the bathroom, trying to look as presentable as possible before walking to class, "(L/N), you're late." You bowed at your teacher, "I'm sorry, sir. It wont happen again." You walked to your seat, which was beside Iwazumi, taking out your pencil case before remembering why you were in the hallways in the first place. You laid your head back to stop the tears as you saw Iwazumi looking at you, holding a peace sign up for a moment before going limp again. 'Think of the consequences. Think of the consequences. The consequences.' You thought.

It was the only thought that got you through the day. The bell rang for the end of school, 'Time for club, loser!' It said, 'Don't forget! You're single now.' 'Okay, fuck you.' You've come to the conclusion that the bell hates you. You packed your stuff up and made it to your locker, grabbing your bags and making your way to the club room to change. You walked into the club room, only seeing the other third years (minus Tōru). "(L/N)," Matsukawa was the first one to great you. You saluted, confusing him. You looked happy. You had a smile (which was disturbing him, the other two not thinking anything of it.) "hey, (L/N), can we talk before you practice?"

Iwazumi put a hand on your shoulder as you pulled your shorts up, "Of course, Iwazumi! What's up?" The other two left, Matsukawa glancing at you before the door closed. "You're acting weird, even Hanamaki and Matsukawa noticed," Well, of course he noticed, "Just, what's wrong? And don't try to say nothing because I saw you in class earlier." It was going to come out sooner or later, "Tōru... cheated on me." You felt the tears gather in your eyes as he looked at you with wide eyes, "He-he what?" You could almost see the gears turning in his head, "I saw him, earlier today he was sucking some girl in the hallway. That's why I was late. I ran into Matsukawa, he knows, too."

Before you knew it Iwazumi was opening (he slammed the door open. There's an indent on the wall) the door, storming out of the room, 'Oh,' you thought, quickly following him. "Oikawa Tōru you show your ass right now!" Oh, he was pissed. It was only the third and second years in the gym, the first years were always last. You walked in after him, face still red and puffy. Matsukawa immediately figured out was happening and gripped Tōru's arm, "Huh?!" He looked confused (and scared, you almost felt bad. Almost) like everyone else in the gym as Iwazumi sinisterly walked towards him, "YOU! You fucking cheapskate! You think it's cool to just go around playing with people feelings?!"

Tōru looked frightened as his best friend yelled at him, arm probably bruising from Matsukawa's grip. "W-wait, what?" He tried backing away as Iwazumi gripped the front of his shirt, Matsukawa letting go of his arm and seeing a red handprint left behind. "Answer me! Huh?! You think it's cool to go around kissing girls when you have a boyfriend?! Huh?!" You wanted to tell him to stop, but it was so fun to watch. Tōru's eyes widened as he finally figured it out. Someone saw him, but who? Who saw him making out with her? He remembered, he remembered thinking he saw someone at the corner but didn't see anyone when he looked. "I-I-I didn't-"

"Didn't what, huh?! Didn't mean to be a cheating scumbag?!" You could see tears in both their eyes, Tōru's streaming down his face, "Th-that's not what I-" "Iwazumi," Matsukawa's voice was deep, deeper than you've ever heard. It lacked his usual coolness. "Let him go," Iwazumi was about to retaliate, "It wouldn't be fair to have our ace kicked off the team." Iwazumi took one last look at Tōru before pushing him to the ground, "Stay, mutt." He mumbled, walking away from Tōru and over to you, taking your hands in his before walking away with you.

After that practice was awkward. The whole team heard what happened and barely listened to Oikawa for the rest of the year, they lost every game that he played in. The school heard and he quickly became the un-popular kid. He thought he was done, only lucky that he ended up joining a pro volleyball team. He thought he was over high school until he received a letter from Hajime, and you. A wedding invite was in his hands, for his ex-boyfriend and ex-best friend. Can his life get any shittier? It can, and it did as he heard you say "I do," to Hajime, it got even worse when he saw you two kiss. The worst of it was when he saw how happy you were. We're you ever that happy with him? He couldn't remember. But oh, did he regret it.
