No but fr what are professor Cha's intentions? We know he's smarter than jiheon, that's one thing. He knew wooju would recognise those pills, so i don't exactly think his intention was to drug wooju cuz for that he could use any other pill. And wooju got kidnapped when he was about 7-8 years old (I could be totally wrong lmao) and at that time professor cha would only be 16 or 17 years old. If that's true, I don't think professor is involved in the kidnapping. He's 33 and wooju's 25.
Is he a red flag? Yup. But one with an entirely different intention, like i don't think he's doing all this to get in wooju's pants.

For me, my theory is prof cha has a plan to make wooju forgot the incident but didnt want to tell jiheon just simply bcus the incident itself took time when his father wad elected. So if the case about the culprit reappeared, it would tarnish his family name. Whether he was the kidnapper or no, a 16 or 17 yo boy is able to kidnap a young kid, especially if the kid has a trust on them it'd make it easier to lure the kid into the trap. The matter of why only jiheon that first come and knowing where to save wooju was probably because the kidnapper is someone he knew and he somehows overheard or knew about the plan.

If you think about it, jiheon has been hurting wooju throughout the story. Manipulation, SA, and now these fucking... Lobotomy pills or whatever. What's crazy is that not even once did he take accountability, and he won't take accountability because in his mind he did nothing wrong. He's not worried about hurting wooju, he's worried about wooju finding out and then hating him for it. For instance when he sexually assaulted wooju badly on the ending of season one, he didn't even acknowledge what he did, he was only bothered because wooju gave him the cold shoulder. The lack of empathy is concerning
I have more theories and speculations about Guwon's dick colour than I have about my own future.
