Fake dating

Chapter 2

The next day, Kaminari and Kirishima walk into class last, holding hands. They walk to the front of the classroom. When everyone's attention is on them, Kirishima says, "me and Kaminari have something to say."
"I'm bi..."
"...and I'm gay..." and then in unison they say,
"...and we're dating!"
Before anyone else has time to react, Bakugo incinerates his desk. Then, Mr. Aizawa walks in. He sighs when he's sees Bakugo's desk as a pile of ashes on the floor.
"What happened?" Mr. Aizawa catches sight of Kirishima and Kaminari. "You know what? I don't want to know. Kirishima, Kaminari, back to your seats. Bakugo, go get a new desk." Bakugo glares at Kaminari as he leaves. If looks could kill, Kaminari would be in the same state as Bakugo's old desk.
Kaminari tries to catch Sero's eye to grin at him, but Sero avoids his gaze, looking everywhere but Kaminari.
At lunch, Kirishima and Kaminari share a bento. Bakugo sits as close to Kirishima as he possibly can without sitting in his lap, all the while glaring at Kaminari who is feeding Kirishima. Kirishima giggles at Kaminari, and Bakugo gets up and stomps off, hands crackling at his sides. Sero spots the familiar shock of blonde hair and spiky red locks and makes a beeline for the pair. When he sees Kaminari feeding a giggling Kirishima, he turns around and opts to sit on his own.
Sero's absence is noted by Kaminari, "where's Sero?" He asks.
Kirishima shrugs and says, "he must have got caught up sparring or something."
That evening, Kaminari and Kirishima were in Kirishima's dorm, studying. They weren't really studying, they had meant to, but they got distracted and started chatting.
In the room next to them, the door was slammed.
Kirishima whispers, "Bakugo is back from the gym."
Kaminari's face lights up, "I have an idea," he whispers back.
