Generally, when a person gets rejected after admitting their feelings to someone, the rejected will try to move on. They certainly don’t stay friends... Unless you’re Shiho and Yul. The two were born on the same day and have been attending the same schools for the past ten years. They’ve also been playing a little game where Shiho confesses his feelings for Yul, and Yul tells him to try harder. The result? Shiho’s become a perfect student, and all the girls at school like him. But now the two have started high school together and it seems like the little “game” they’ve been playing might have more players. The rules are changing quickly – is it too late for anything more to develop between Shiho and Yul?
