I think it's because Professor Lee never had someone to nag and dot on him which is why he feels weird Jaehee acting like that.. I'm happy for Professor ❤
@Duraau_21 are you blind??? Simoon also gave him attention and took care of him . So it's not a 1st time. (It can be as friends too not lovers) But surely it's not his 1st
@Svt Let's wait for other episodes to decide what kind of care and attention Simon gave him... Can't judge on basis of information I got form this and previous episodes... Given that he impregnated but isn't mated/married to professor.
