In chapter 54 the professor mentions he has a younger sibling with a big age gap he doesn’t know well, I can’t remember fully but am sure we don’t know who Jiheon’s father is yet, which leaves room for it,
That plus both professor’s father being a big politician somehow involved in Wooju’s original kidnapping and Jiheon’s mother also being a celebrity who is quite absent in Jiheon’s life, it wouldn’t be surprising for their parents to have met, and it might explain the professor’s obsession with Jiheon. I can’t remember the chapters but tbh it’s been such a long hiatus it might be easier to have a quick reread.

Personally I don’t think his obsession is romantic since him helping turn Wooju into an omega would be unhelpful if he was his rival, so i feel he may want to take advantage of it so he can blame Jiheon and see his fall. Plus seeing Wooju actually turn into an omega i’m not sure the author would entertain a alpha x alpha potential pairing imo. Honestly though who knows, again nothing’s been confirmed!

The prof likes Blondie right?
Idk but even when we first only got a glimpse of prof at the very start he looked at a pic of Blondie, not the redhead so he’s doing all that either to get blondies attention or some kind of revenge?
Prof obviously isn’t interested in redhead and oftentimes idk seems a bit disgusted even by redhead (like he threw the jacket away bc of redheads pheromones on it??
Or am I misinterpreting??
