you were a stranger to Tsukasa, and vice-versa. you didn't know each other, but went to the same school as him.

there was a large difference between you two: you were bullied a lot, and Tsukasa was an egotistical student who got a lot of positive attention, unlike you.

one day, Tsukasa saw you getting bullied and actually felt horrible.

"ah... pardon! how about two tickets to my next show?" Tsukasa asked the bullies, in order to distract them from harming you. the bullies left after.
