Your whole room was all loud, Chizuru's voice filling the entire room. She was playing a video game she sucks in, so she's yelling all kinds of curses and complains

While you, in your own room. We're just staying quiet at the corner of the bed. Both of you have always been close since childrens, making everything between you two comfortable

But honestly. Chizuru was dense, she never even notices the signs you gave that you like her. Though you can't blame her, she is quite an airhead
