It's okay if Ji-heon does it, not someone else. Haven't you been in a relationship before...where it's okay for you to do something to your partner but not okay for someone else to do it or try it. It tends to make you made, right. Example, like it's okay for you to call your partner babe but if their coworker were to call them that in front of you and be doing it all the time, you'd be made because you know they are doing it on purpose, because you've already warned them off of your boyfriend or girlfriend, and yet your partner sees nothing wrong with it and thinks your overreacting...until they wake up to seeking you were right about them.
I mean he is doing smth the mc is unaware of and the mc might end up with a trauma when they become aware of the things ml is doing to him and druggin someone to convert their secondary gender isn’t a normal thing even if they are lovers.
I mean why is he so angry about the same thing he is doin ?
