Rui and Tsukasa weren't really close, during highschool nor now in college. Tsukasa had always admired Rui from afar, and would often give him some desserts or things, Rui's friends noticed immediately

Then one day, right before they graduate, Rui's friend made a bet with Rui.

"Make Tsukasa fall inlove with you before graduation and I'll give you 10,000 yen. After you did dump him!"

Rui immediately agreed, today was the day that Rui will try to make Tsukasa fall in love with him
