Please, tell me the title.

This is a bl webtoon where the uke is an intern of a certain company and he was put under who is called as the "unofficial manager" because he's incredibly good at his work but he refuses to be promoted, their departrment is at advertising department. Another info is that the uke had a long-time crush when he was still in a uni and joined a club because his crush is a member of that lgbt+ club and he met there his friend who I think is a lesbian and then at some point the uke decided to stop his feelings for his crush beause he thought his crush loved someone else, and now the uke discovered that his crush had a relationship to now his boss/boyfriend/fling.
