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.
