A romantic and melancholic love story behind a red umbrella.

A collection of six short stories that revolve around a chain of people.
1. No one ever asks Kie out. She’s 18, so her high school life is ending soon! Her friend tells her to eat a piece of candy that works like a love potion. All the guys are into her now, even her good friend Shimon! But when she really falls for him, she worries that their love is a lie…
