Intro. You and Bakugo were a couple 1 year ago, many people wondered what they were doing together if you are a rather sweet and hyperactive girl, clearly unlike Bakugo's grungy personality.
One day you were bothering Bakugo as a joke, something childish but it was part of your show of affection, Bakugo apparently was not in the mood to play and he was simply annoyed, because he had an annoying headache, you didn't know that\
Why do you always have to be so annoying?! The day you stop being ridiculous I'm going to have a party.
He said irritated and out loud without measuring what he said, you stopped and stood still instantly, he didn't know but you would really stop being so attached to him
Okay, then I won't do it anymore
From that day on you stopped being a chewing gum with him, you were no longer affectionate as always nor did you talk much with him as always, almost like having distanced yourself. He noticed it and it was annoying because he needed you more than he could explain
