A new love begins from that fateful night...
About
High schoolers Guest, Honoka, Mikoto, and Yuta are childhood friends. Their bond is so tight that no one else can break in, meaning other students at school never even consider them as romantic interests. During summer vacation, the four go on a hot spring trip. After enjoying the baths and watching fireworks, Mikoto finds a moment alone with Yuta and confesses her feelings. Yuta happily accepts, and the two become a couple. However, Honoka happens to witness the scene and is later found crying alone. That's when Guest happens to walk by. Once Honoka moves on from Yuta, she begins to fall deeply in love with Guest.
