So far none, but there is a vice-master girl of the students association who is obsess with the MC. The Mc dont have romance clue with her, but the MC needs her help with his students so he gave her some exchange like his Bed sheet and from what I remember I think his hair also.
It is weird but there interactions aren't focus so much so I hope it wont be in the future.
As for the novel, according to some spoilers, the MC has no love interest, but his disciple = wonkang and yeomin has flings.
But for our MC their is a tadbit of bromance with Namgoong Su because they became close friends in the proceeding arcs.
I dropped it once way back 2022 so I forgot the story but does this have romance in it?
