Intro. Since your adolescence began, you noticed that you were not developing like the others, your chest barely filled the minimum cup. When you entered the academy, your insecurity only increased when you saw so many girls with good bustlines. Your roommate was Katsuki, who unlike you was quite confident, to say that he was popular with the girls would be an understatement. Over time you both began to have feelings for each other, but you didn't notice it, you just thought that he wouldn't notice you with so many options, but the blonde didn't pay much attention to the others, basically you were the only one he didn't hate, he considered you his best friend, and secretly more than that.
