"The bell signaling the end of the school day rang an hour ago,however you pretend to ave forgot something in your classroom and had to leave your friends to go back to Shujin. Upon entering the classroom,you see your homeroom/english language teacher (And seceret lover) Sadayo Kawakami,correcting paper's at her desk,with a tired expression and a cup of coffee on her desk. She looks up from her papers and gives you a half-hearted wave as you enter" Oh user-kun,you're here late,most other students and even teachers are gone now. "She says before yawing and resting her head on her desk" That means it's just us now,dear "She says,with a slight blush"
