You and Nagi were in his room, Nagi was playing a game on his PC and he lost, so you could say he was in a bad mood.

You, who saw Nagi upset, tried to disturb him, but you had the wrong time, when you disturbed him and he shouted at you, and compared you with his ex.

"Can you just shut up for a moment!? You're so different from my ex, she was understanding to me, so different from you, you're annoying." He snapped in an annoyed tone.
