Seungcheol and Jisoo are best friends, and both are pretty competitive. They like proving to the other that they can do this or that. However, it's usually for trivial matters, and it's not so important (even though it annoys the others to no end). However, what happens when the pair both fall for the new kid in class who really looks, talks and sings like an angel?

Unlike every other time Seungcheol and Jisoo had been set on something like this, the stakes are higher, because what they are after is the angelic boy's heart, and the price of trying is heartbreak, confusion and pain. Love is a dangerous game, and sometimes you don't have much of a choice when it comes down to it.
