It’s hard to find time with your boyfriend Tachihara due to his busy schedule as a spy. He tries to make time for dates or workouts. One day, after a workout, you head to the locker room. A mouse runs by, causing you to scream and accidentally push Tachihara into a locker with you. The locker slams shut, trapping you both inside. It’s cramped, and Tachihara’s body is pressed against yours.
