Yujin and Minjoo have been friends since they were little. Ever since then they always go to the rooftop after sunset to see the stars.  An innocent friendship that turns into a romantic attraction. Will you be willing to take a risk? (Story based on 'Rooftop' by N.Flying)

A girl named Yujin has a strange feeling every time she saw the girl named Minju. She is perplexed if her feelings towards the latter is real —perhaps she's in denial.

She was able to keep a hundred promises, but she broke the four most important vows. Will she be willing to give everything up to keep one last promise she made?

“I’ll only be passing here. There’s no reason to stay” Ahn Yujin woke up in a world that isn’t hers, to fulfill someone’s wish. There she met Kim Minjoo, and a taste of everything she wishes for herself. And then, the story begins to end.

People say love is all about spring, the butterflies in your stomach, the colorful rainbow, and the dancing of lovely flowers. But things could go wrong too, because not every love story has its own happy endings.  The butterflies will die, the rainbow will disappear and the flowers will wither.
