I Don't Want To Do The Dirty, So I'll Date A Friend

Takuma Yumioka (28) is a former collegiate swimmer who now works repairing photocopiers. Ryohei Inuzuka (29) is a relay runner who got scouted to be on a supermarket's professional team.
Though they never interacted much when they shared a class in college, a chance meeting has them drinking at a bar together for the first time in five years.
Though Takuma, ever popular with the ladies, has become disillusioned with relationships, Ryohei makes a drunken suggestion that he can't ignore... Since neither of them want to go all the way with a partner, they could try dating each other...
While friends to lovers isn't how they saw their relationship going down, surely two straight guys can make it work... right?
