Bakugou waits for about fifteen minutes until Sero arrives. He gets into Sero’s car and shuts the door. He puts his seatbelt on. (Always wear a seatbelt kids, or don’t, and don’t blame me if you get hurt.) Sero starts the car and starts driving towards the dorms. 

“So what did you need me to pick you up for?” 

“I did- almost did something bad, really bad.”

“Oh um what did you do? If you don’t mind me asking.”

“I’ll tell you at the dorms. We’re gonna go to your room.”

“Ok Baku.”

The rest of the ride is silent. The only reason Bakugou trusts Sero is because he knows about how Mitsuki is and how bad she can be. Sero was there through some of Bakugou’s worst moments and he didn’t tell anyone. So Bakugou knows he can trust Sero. And it’s not that Bakugou can’t trust Mina, Sero, or Kirishima, it’s just Mina and Denki are loud and there like little siblings to Bakugou, and Bakugou doesn’t want to drag Kirishima into his problems because he thinks Kirishima doesn’t deserve that. They arrive at the dorms and Bakugou hides his face with his hood because he knows he looks like a mess. They immediately go to the elevator, avoiding the people in the common room. Bakugou feels eyes on him but he keeps his trained on the ground as he steps into the elevator. Sero hits the button for the third floor. The doors open and they go to Sero's room. Bakugou notices the signs next to Seros room. On the left Iida and on the right Denki. There’s no light on under Denki’s door so Bakugou assumes he’s either not there or sleeping so Bakugou shouldn’t have to worry about eavesdropping. Sero opens his door and they go inside. Sero sits on his bed and Bakugou sits in his chair, literally his chair because he’s the only one who sits in it. Sero looks expectant and Bakugou can tell he's waiting for him to talk.

“Ok so, um, I don’t know how to start this,” Bakugou explains nervously, he fidgets with his shirt and chews on his lip.

“It's ok take your time,” Sero says in a serious tone so Bakugou doesn’t think he's pitying him.

“Ok so I don’t want to name names but, ok, me and someone almost kissed and I don’t know what to do.”

“Ooo do I know her?”

“Um well you see, it's actually... him,” Bakugou stated on the verge of tears. Sero looks shocked, his jaw dropped. Sero calms down and clears his throat then says in an excited tone,

“Well do I know him?” Bakugou then looks shocked, he wasn’t expecting Sero to be ok with the fact he almost kissed a guy.

“Um actually you do, but anyway, so I almost kissed him, and then someone interrupted us and I freaked out and hid from him and then he left. But the worst part is that I really wanted to kiss him.” Bakugous face turns bright red as he remembers his almost kiss with Kirishima.

“You know it's ok to like guys right? I like a guy.” Bakugous jaw drops. Sero has never told him this before.

“Wait- wha- who? Can you tell me who?” Bakugou says curiously.

“Well, ye- uh no because you know him and I can’t,” Sero says blushing.

“Oh ok, well anyways what does it mean if I’ve never thought about kissing anyone other than this one person?” Bakugou says fidgeting.

“Well.. ok so hmm let's see, so if it helps I'm bisexual which means I like girls and boys. And you said you’ve never thought about anyone like this before right?”

“Yeah.”

“Are you really close to this person or are you just attracted to them.”

“We're ‘best friends’ I guess,” Bakugou says without thinking first. After a few seconds he looks up at Sero, Seros smirking. ‘Oh, shit he's had to have found out it's Kirishima.’

“Sooo is it... Kirishima?” Bakugou’s face turns bright red and he has to look down at his shoes.

“Um.. yeah..”

“Aww that’s so cute Bakuu~,” Sero says in a teasing tone.

“Leave me ALONEEE,” Bakugou yells at Sero out of embarrassment.

“Ok anyways do you find anyone attractive other than Kirishima?”

“I don’t fucking know. I only realized this when we almost kissed.”

“Hmm ok, let me see if I can look this up real quick.” Sero pulls out his phone and looks something up.

“Ok, so I looked up, ‘what does it mean if I'm only attracted to someone that I really trust’, it came up with an article about demisexuality. If you want I can send it to you so you can read it and see if it fits you.”

“Ok. Thanks, Sero.” Bakugou gets out of the chair and leaves. He goes to the elevator and presses the button for the fourth floor. He hears his phone ding and checks it. Sero sent him the link. He decides to open it when he’s in his dorm. The elevator doors open and Bakugou steps out. He goes to his dorm, not without checking if Kirishima’s in his thankfully it doesn’t seem like he is, and he lays on his bed. He skims the article until he sees ‘To put it simply, demisexuals only like someone once they've formed a strong emotional connection.’ Bakugou kinda stares at that line for a while. He tries to think back to when he maybe started to feel something towards Kirishima. They got really close after the Kamino incident, and ever since then they’ve been stuck together. Kirishima lets Bakugou stay close to him at parties. Kirishima lets Bakugou hold onto him at the movies. Kirishima calms Bakugou down when he’s having a bad day. They recently started holding hands. Bakugou tries to think about how he felt with all of that stuff to compare it to the article. He felt happy. He felt butterflies in his stomach and his face heat up. He felt like he could really trust Kirishima. Like he could tell him anything. Like he would let Kirishima do anything with and/or to him, and he would still trust him. Holy shit. 

He’s demisexual and he likes Kirishima.
