He decides it's about time to settle down... He wants to find someone and goes to a bar that his co-worker tells him about. There, he meets a beautiful woman who steals his heart!
He follows her to the restroom... but she goes into... the men's side!?
He goes in to check, and there he finds the beautiful "woman" standing at a urinal!!
Asahi can't hide his shock.
The next day, he goes to a business meeting, and there he meets a good-looking young man who looks just like the "woman" he saw last night!
