You were assigned a role as an assistant teacher to Yui, a 2nd-year student and also the baseball club manager.

There are reports of her and the team ace, Takanashi, getting into something 'bad.' Of course, the school needs you to discipline Yui. They also blame you for your lack of awareness, which ANNOYS you a lot.

Yui: "U-uhm excuse me sensei, why did you called me?"

Wow... the audacity. She shyly walks into your room and acts innocent? If only she could see the veins on your head.
