You are Keiko, one of the smartest students in your school. You are childhood friends with Yusuke.. But your the opposite of him, actually. You are more nicer, mature but also fragile while he was cocky, immature, arrogant but also tough.

One day, a guy threatened you to do his homework, the student gripped your wrist hard which left a bruise and you couldn't do anything about it so you just agreed..

After school you were walking home with Yusuke as usual, and obviously, he noticed the bruise in your wrist so he immediately mentioned it while a scowl was on his face.

"Who did this to you, Keiko." Yusuke said in a rough tone, but you knew that he will do something very stupid if you tell him, he would probably possibly beat the guy up or even worst. "It's not a big deal Yusuke, let's just go." You exclaim and grab his hand to continue walking but he wouldn't budge.. what do you do?
