That was so sweet sex, but please, someone could explain the plot to me ? XD I'm at lost, he has gone somewhere far away, and the "name thing" got me even more lost. x)

Copy pasted this from Spiritual-Yogurt:
kim chul soo is the real name of the son of the president of jodong Pharma company while Han Sang Yoo is the name of the omega male lead who was experimented. in the story Jodong Pharma's president swap their names so that the prince would be wed to to his beta son so he could get Alimony even if they divorced then the real Han Sang Yoo was told to accompany the son because the pharma company wanted to check manifestation (for experiment) from the omega male lead if he gets closer priximity to the prince who is an alpha. although the uke doesnt have any idea on what they were planning he just know tht he needs to accompany the son, take his medicines and report any reactions.
Correction: the son of jodong pharma took the uke's name the son's real name is not kim chul soo but lee han seok.

Han originally went by the name of Han Sang Yul but before they went to the palace, another person (the guy who was hitting him earlier on) took his name so that they thought that he was the real Han Sang Yul. At that time, everyone just thought Han was someone extra staying at the palace from the company to help “Han Sang Yul”.
The prince just figured out that Han is actually Han Sang Yul (because Han kept answering to the name as if it’s his) and has most likely experienced terrible experiments due to how he is.
Man, that’s a lot of “han”…

He could still wait for him to be of age, mostly because his mind seems to have grown while he was with him, they'll understand both that it will have to wait (at least for a while because his body wouldn't even take it and if there's love, they wouldn't want to hurt each others). I don't think the author wanted for it to have that pedo vibe, but more about a complicated love story throught hardships, and space and time. Body and mind doesn't always pair the right way, a lot of people are going throught that fact for many different reasons (and many different ways). The author didn't show the joung boy version doing dirty things so maybe just read the plot for what it is and not what it could be?

Still there... Still doesn't know why, because the high level of toxicity is too sudden and too vicious. Yes, obviously it could be about traumatizing and all, but that's... really too vicious and too extreme when the beginning was so good (but also not entirely healthy already... ) C'est la goutte de trop.
I just don't even know why i read this until this end...
