Yuki Nijino's manga / #Gym(3)

Office worker x personal trainer.

Despite it's flaws, I think it's cute. And ngl the seme is kinda similar to me in how we give up (or try to at least) so quickly. - Gym instructor falls in love with a bartender who then goes to his gym to look good for his unrequited love.

Ch. 7 end Dude goes to the gym to bulk up and meets a trainer who has his ideal body. He's unknowingly attracted to him and the trainer is conveniently gay and likes him too.
