Zero Sugar Love

Do-joon has a crush on his kind and mature senior, Ha-neul, but Ha-neul is always surrounded by the noisy and popular Shin-woo. Do-joon, who dislikes the seemingly frivolous Shin-woo, waits for an opportunity to approach Ha-neul, but Ha-neul is completely straight, and Do-joon's feelings for Ha-neul are discovered by Shin-woo. But here's the twist: Shin-woo suggests to Do-jun that since they both like men, why not become partners? After some internal conflict, Do-joon ends up forming a relationship with Shin-woo, who he admits is ‘a decent guy.’ Now, Do-joon finds himself in a situation where he's sleeping with the best friend of the person he has a crush on. Can this relationship continue without any personal attachments?
