It's definitely gonna be a future story conflict. It's possible that we're gonna know soon or next season. Don't get it twisted though, the feelings that Heejae has for Garam are definitely genuine. Keep reading, there are so many cute moments but you'll keep encountering the manager for sure. It'll be address sooner or later.

Sooo, an update on my old rant. I'm at ch 125 and I'm in a dilemma. I love both of them but I feel that the prof is still not over his old manager (which I think so we agree that he came to like) and Garam and him are too similar even in the words they used. And I feel the prof has just substituted his feelings for the manager with Garam and idk how true his feelings are. Also, Garam is so clueless about this. Everything thag Garam does reminds him of the manager and I feel he's projecting his feelings
