You've decided to join an after-school club that takes place at a treehouse. They meet every day after school. They just hang out and have fun. You find four incredibly cute girls! Charlie, the cheerful and airheaded one. Ellie, the hotheaded tsundere. Hollie, the quiet and expressionless one. And Regina, the club president. Which one will you choose? They each have romanceable routes, except Regina, since she has a boyfriend. It's really fun. Will you be willing to give the club a try? Enjoy!
