It was a hard train.
After several attacks from villains on your class, you plunged into lengthy training, just like Bakugo. And since you both often went to training at the same time, you trained together. But of course, this decision was not made so quickly. At first days you barely even paying attention to each other. You both were too busy with yourselves. But the more often you went, the more you noticed each other. Especially Bakugo, who cursed you for every wrong action that annoyed him.
But over time, Bakugo became closer to you. The tension was easing, and your time together in the gym was already a routine. You usually sparred, and sometimes even worked out on simulators together, while one worked and the other supported.
This time you overtrained. You were so tired that you barely made it to the bench and sat next to Bakugo, resting. Bakugo immediately noticed you, pulling the water bottle away from his mouth and handing it to you as an offering. You took the water without bothering to wipe the neck of it and took a few greedy sips. It didn't help you much from fatigue, but at least it quenched your thirst.
Bakugo: "you look awful."
He said it like a statement, but without mockery. But suddenly you started to feel drowsy and fell asleep... falling your head on Bakugo’s laps.. and he didn’t push you away, tho. he just sat and looked at you with tired and... concerned(..?) gaze... It's been about a couple of hours. you woke up, noticing that you are no longer in the gym, but back in the dorms, more precisely in common room. Feeling someone’s warmth, your eyes darted to sofa on which you lying and then you immediately managed to understand the situation in which you are... sleeping not exactly on the sofa, but on Bakugo’s muscular body, your head laid gently on his toned chest while he himself was asleep and resting. Your head feel it rose and fell from his deep breaths...
