It's definitely not for everyone especially if you're sensitive to things like SA since it has been shown multiple times (perpetrated by the mc). I would say read the first chapter (which is a time skip) if it isn't a sensitive topic for you, and make your decision then because as the story goes, it will ultimately lead to that. It's pretty early to tell the extent that the author will show these things and I'm not far enough in it to gauge whether they will romanticize the toxic relationship to the point that the abuse turns to love which I've seen far too many times. I would go into it with caution but I do stand by the characters being written well through a psychological sense SO FAR :)
Finally someone said it , people keep blaming Hesso for no reason while overlooking the facts how much he gone through expecting him to behave all kind and perfect, also Cha behaviour which sort of makes it triggering Heeso's behaviour past trauma and upbringing of someone brings lot into someone's character so far author is good on this fact of making Heeso character.
The psychological aspect of this is really well written. Heeso acting the way he does makes sense based on his past experiences. He's emotionally immature and at this point probably equates sex to love. He doesn't know what love means to begin with. At least not healthy love.The behaviors are inexcusable ofc but explaining reasons WHY somebody does something versus excusing the behavior are very different.
Taekyung also has an unhealthy attachment to Heeso but in a much different sense. He feels the responsibility put on him by Heeso's mother and felt like he couldn't disappoint her because of everything she did for him, but he never wanted to cross that boundary of actually getting involved with Heeso because nothing good could come of it... as we've seen already. He's desperate to keep Heeso safe, and bc Heeso has already expressed suicidal thoughts/actions, he most likely feels like he has to go along with his whims to keep him from spiraling. Although by doing this, he's encouraging the bad behavior shown by Heeso. The more he gives in and even participates, the worse the situation will get. Especially if at some point Taekyung tries to leave. Which I have a feeling is going to be a leading cause of what was shown in the first chapter.
It's a very compelling story the dynamics are obviously very toxic, but the characters have depth. I'm worried the abuse will be romanticized one way or another, but I'm curious to see how the author plays things out.
