Happy Day.

Emily is a typical "stomp girl." Believing the grass is always greener on the other side, she flirts with other people's boyfriends. One day, she falls in love at first sight with Naomi's boyfriend, Souta. With the help of Shota, a stalker who is also in love with Naomi, she tries every trick in the book to get Souta. However, her over-the-top nature backfires, and the scheming Emily becomes consumed by her own schemes. (R15+ version premiered at the OP PICTURES+ Festival 2025).
