(WARNING! Mention of self-harm) 

It was after class, and the students were heading to their dorms. "Ugh, training was so exhausting," Denki complained, groaning. "Heh, at least it's the weekend, buddy," Koy said with a smile. "Hey Koy, how come you're wearing your jacket?" Kirishima asked, knowing that it was almost 90 degrees out. "Oh, uh...I dunno, just wanna..." Koy said, pulling his sleeves up a bit. "You gotta be hot dude, here take it off," Sero said, pulling at his jacket. "DON'T!" Koy yelled, pushing him down by accident. "What the heck?!" Sero asked, seeming upset. "S-sorry, I just...I don't want it off..." Koy said, helping him up, then rushing into the dorm. 

"I wonder what was up?" Kirishima asked, seeming concerned. "Do you think there's something wrong with his skin?" Denki asked. "No way, he has like, perfect skin, maybe he has a bad birthmark," Sero thought, all of them trying to figure it out. "You know, he's never worn a short sleeve shirt," Denki told them. "Yeah, and whenever we swim, he has a swimming shirt on, and usually waits to change into his clothes when no one else is near," Kirishima told them. "What the hell you extras on about?" Bakugou asked, walking up to them. "Have you ever seen Koy with a short sleeve shirt?" Denki asked.

Bakugou's expression was saddened. "No...but I know why..." he said, looking away, then looking at them. "Why do you idiots want to know?" he asked. "Well, it was hot, and I tried taking his jacket off, but he pushed me down," Sero explained. "Well...it's none of your business, you better drop it now," Bakugou told them, walking away. "Is it something embarrassing?" Denki asked. "...Just don't worry..." Bakugou said.

He went to Koy's room, knocking at the door. "Who is it?" Koy asked from the inside. "It's me, dumbass, let me in," Bakugou told him. "Door's unlocked," Koy let him know. Bakugou walked in, seeing Koy sitting at his desk, his jacket off. "Door closed?" he asked Bakugou. "Yeah..." 

He looked at his arms, seeing cuts. "You made those extras out there start theorizing about what you're hiding, none of them are right though," he told Koy. "Okay...I didn't mean to push Sero, just...it's hard to share this with them..." he told him, sighing. Bakugou walked over. "Hey, you were in a dark place, I'm not saying it was the best thing, but it's what you did to deal with your old hag mom. I have to say...it was hard to watch when she found out..."

We were about 13, and your parents needed to come over to do a conference they couldn't do over the phone. One of the teachers saw your arm and let them know. Your father was worried, but your mom... "What the hell is this for?!" he yelled, grabbing your arm. "M-mom, let me go! It's nothing!" you yelled. "Nothing? Let's ask your sister and 'Friend'" she said, dragging you into the living room. "Look at this, Koy thinks it's cool to give himself scars! He thinks he's some kind of thug, might as well add to it!" she yelled, grabbing a knife and cutting into your skin...my mom managed to stop her before she went any further, and she spent a night in jail...but it was so awful...

"Thanks for opening that back up..." Koy said, laying his head in his hands. "I didn't bring it up to make you mope," Bakugou said, smacking his head. "I brought it up to prove that you didn't let Satan break you," he told him. "If I didn't break...I wouldn't have done this..." Koy said, showing his arms being cut from the bottom of his wrist to above the part behind his elbow. "I've been broken..." "No, you're not, idiot!" Bakugou yelled. "You're still here! You're still alive! You and Kay have been through Hell, and crawled out with big ass smiles! You're gonna have to tell them one day, not today, but they deserve to know," he told him, pulling him into a hug. "You didn't let that bitch kill you, don't let her do it now...wear those scars like badges, you hear me?" he asked. Koy teared up, holding him tight. "Thank you...I needed that..." 

A few hours later

Koy wanted to talk to his class in the main area. "Hey guys...this is a hard thing to do, but I gotta show you guys something..." he told them, wearing a jacket. "Is everything alright?" Todoroki asked him, wondering what was going on. "Something new with your quirk?" Mina asked with a smile, which made Koy chuckle. "Heh, nah...just a secret I've hidden..." he said. Kay's eyes widen a bit. "You sure? You're usually... self-conscious..." she told him. "Yeah...I'm sure," he said, then took his shirt off. 

Everyone's eyes widen. "A...are those cuts...?" Momo asked, covering her mouth. "Yeah...I used to cut myself...I only told Kay and Katki because I knew I can trust them...but it's also something I used to be ashamed of...I thought they were just to remind me I used to be weak...I had to resort to pain to escape the bad...but now, I see that they remind me I can be strong and that I'm not a victim...I'm a survivor..." Koy told them, having his arms out. "They prove you can do anything...you've never been weak," Deku told him, which made Koy smile. "Yeah...heh, I know it's not much, but wanted to show you guys," he said, about to put his shirt on, when Ochaco and Mina hugged him. "It's a big deal! We're glad that you trust to show us!" Mina told him with tears in her eyes. "Yeah, we're always here in case you're ever in a dark place!" Ochaco told him, sniffling. "Heh...thanks..." Koy said, hugging them back. 

It felt so comforting...like he was part of a real family...
