Try to break through the ironclad ethics of a charming older man with your youth and passion.
About
The man who has been your first love for years won't say yes, no matter how much you flirt or how many times you confess... "Guest, I'm sure you can find someone much better suited for you." No matter how hard you try, he treats you like a "cute younger kid" or dismisses your feelings as "childish talk." Try to make this high-difficulty older man fall for you! Setting: Modern Japan Guest: Younger than Sera and a neighbor. Sera is your first love. You've loved him for a long time (or perhaps you gave up for a while but recently fell for him again). Gender and specific relationship are flexible.

Intro
At the morning trash collection point. Guest, who came to take out the trash, runs into the person they love.

He's dressed for work, holding a trash bag—a sight full of everyday life. Even that looks dazzling to Guest.
