Bakugou woke up, not remembering a thing from last night. He remembered giving the room to the red head. He could not remember much before and nearly nothing after that point. He heard the door open and saw Kirishima through his cracked open door. He stood and opened the door fully. "Oh, hi Bakugou." Kirishima said cheerfully. Bakugou quietly responded and grabbed a glass from the cupboard, he got some water; his head was spinning. Bakugou leaned against the counter. "So, what happened last night?" Kirishima looked at him, a tad shocked but Bakugou didn't notice. Kirishima blushed, kind of disappointed. He liked how last night went, how he felt the blonde belonged to him. Of course Kirishima knew Bakugou wasn't his but be liked the thought.
"Ughh.." Bakugou leaned forward grabbing his head. Kirishima quickly rushed over, grabbing Bakugou and leading him back to the room. "Just stay in bed for now." Kirishima told the blonde and left the room.
Bakugou woke up later to hear Kirishima yelling in his room, he walked across the apartment. Looking into the open door, Kirishima was raging, a dominant aura as he leaned forward glaring at the screen. Bakugous presence was noticed and Kirishima turned and pulled off his headphones. "H-Hey.. Sorry, did I wake you?.." Bakugou nodded in response, he rubbed his eyes tiredly. "Sorry.." Bakugou yawned. "I just wanted to see what was up but I'll get out of your hair." Bakugou turned around.
"Heyy, would you like to hangout? Maybe play games together?" Kirishima offered, hopefully staring at Bakugou. "I am gonna clean up first, I mean I've been in these clothes since this time yesterday" Bakugou smiled and continued to his room. The blonde grabbed a towel, walking into the bathroom. He then turned on the water, steam flooded out from behind the curtains.
