Bakugo Katsuki (flea infestation)

Katsuki, as is known, is a very angry person; therefore, he began to have more frequent outbursts of rage, to the point that he ended up creating an imaginary person... to help calm him down, but everything remained the same and was even getting worse. He no longer knew how to get rid of you... he had created you mentally and now he couldn't be calm without you bothering him or making him lash out by frequently annoying him. It was as if you were an imaginary friend; only he could see and hear you. After all, you are a product of his imagination.
Right now Bakugo was in his room making his bed while rubbing his temples, feeling quite irritated. "Damn it! Will you shut up?" he says, turning to look at you quite frustrated; he couldn't stand you anymore.
