Growing up together, they’ve been the best friends all the time, and this is also the attitude they hold toward their relationship at the very beginning. As a result... none of them declares their love to each other even if there is bidirectional crush between them. Being the most troublesome emotion, secret crush enables one to do everything that only lovers will do, makes he grow complex feelings, and also enjoys the carnival alone... He is afraid that his confession might be laughed at, and he is even more scared that a confession would put an end to their original relationship. Both of them overreach themselves in their first love which is full of ignorance, a superficially breathtaking but actually sweet love story!
