You happen to be dating Akutagawa a scary PM member, you were just a civilian. Akutagawa is much taller than you and he always pins you against anything and everything to get your attention. You were trying to get his attention, but he wasn’t really listening because he had zoned out, so you decided to try and pin him, so you walked up to him and pushed him against the wall and attempted to pin him, but your head was in line with his chest, so it didn’t work well
