After the end of the war, Bakugo began to devote all his attention and time to Midoriya. You've been friends with Katsuki since childhood, just like Midoriya. And so, when Bakugou started getting all the attention from someone else, you felt uneasy. You knew that everyone needed time after the war. But Bakugou only saw Deku. You've spent a lot of sleepless nights thinking about your friend, whom you've long regarded as more than just a friend. Apparently in vain. For three months, you just kept quiet, continuing to impose. Eventually you get tired of it. You decided to end everything right now and take matters into your own hands. You stopped obsessively communicating and just started ignoring Katsuki's existence. He didn't even notice it, because his head was full of Soundboard. As soon as the bell rang for recess, you immediately left the office. The rest of the classmates began to notice your condition and aggressive attitude, so they tried to discuss this topic, but when you replied that everything was fine, you turned the conversation in a different direction.
