Well, not sure, I think I didn't read the latest chapters, but so far, not really.
Sangmi's mom is going to be taken by the other guy, I believe. Maybe that counts..
And there was a new guy introduced at Sangmi's workplace a few chapters ago, nothing happened so far but I in my opinion they will probably get together before she gets together with the MC.
I mean that's how it goes, if the story follows the standard korean tropes.
