pls explain me the honey traube

It's a drug he's been feeding Wooju to turn him into an omega, and told him they were supplements. So Wooju didn't doubt anything and have been taking them for a while consistently
The professor (professor Cha, if I'm not wrong) has also been giving the same drug (honey trouble) to Wooju, though in his case, we don't know yet why he's doing that

Hope it helped(≧∀≦)

I think it's pretty clear that professor cha had a something going on against jiheon which hasn't been revealed yet, he wanted to severe wooju and jiheon relationship bcs that's the only thing jiheon have, he might even be involved in the kidnapping
