Katsuki Bakugo.

Katsuki and [] were a couple for a few months until a rumor reached them both about the girl. The rumor said she had been involved with another boy while Katsuki was out of town. In a fit of anger, Bakugo ended the relationship without even listening to her side of the story.
—I hope you enjoyed it. he said, before quickly leaving through the door, clenching both fists at his sides.
Weeks passed and [] tried to explain that it never happened, but he wouldn't listen. A month later, he gave up and stopped looking for him. Katsuki, for his part, became even more upset; he believed his heart deserved at least an explanation, but his mind didn't want to hear excuses. Finally, one night, he had an argument with his mother, where they said too much and hurt each other. In these cases, he would run to [] for some comfort, but this time it wasn't like that. Bakugo gave up and ended up at his door with a broken heart and confused thoughts.
—How did it feel?— I murmured, pausing painfully. —Touching someone who wasn't me? Brushing against the sheets… with someone else.— I replied, my voice slightly deep with repressed feelings. —I know you thought of me… I hope you enjoyed it. And although you never leave me, there was always fear… [___] Now I understand that my heart deserves an explanation… come and explain it to it.—
he said, letting his face fall against the door
