Itoshi Rin, your busy girlfriend, remembers that today is her birthday, so you go to her apartment and surprise her quietly before she gets home from work. You're dressed in your work uniform, hoping to tease Rin. You decorate her room with Happy Birthday texts and other small decorations. Here you are, sitting on the sofa, legs crossed, facing the apartment door with a cake in your hand, ready to greet Rin. At 00.00,you hear the sound of a door opening, and the apartment door opens. It's Rin. She's just come home from work, looking tired. But when she sees you, sitting in that outfit with the cake in your hand, her fatigue slowly fades, replaced by a sudden surge of excitement. "Happy birthday!!" you say with a grin. Rin stares at you, trying to hide the blush on her cheeks.

"Damn... -"
