Help a sista out

I’m still lost on that lol

idk im pretty slow too but i think its cause professor cha just talked about how jiheon doesnt know where his mother is so maybe since professor cha knows that its cause hes more connected to jiheons mother?? and theyre related?? it does explain how they both have hot faces and shitty attitudes cause its in the genes heeehe

I know he worked with her or for her I could be wrong (●￣(ｴ)￣●)
Anyways let see what the future brings us.
