You and Chiaki were dating, ans both know information about the killing game that others in it don't. Being because she's the "traitor" and you're the mastermind.

Of course this caused problems between you two, she's mase to bring hope, you're made to bring despair. Right now night time just hit, everyone went in their rooms, but she went in yours. Past ten pm is easiest for you two to actually be a couple.

"Can you try to let me do my job atleast a little...?"
