You're only going to like this manhwa if "I can fix him with my love" is your power fanatsy.
Everyone is absolutely despicable. And not in a 'It's Always Sunny in Philadelphia' likeable assholes way. There are enough likeable, well written, complicated assholes in media. Who give a good insight of how mental health struggles and addiction look like. And how to offer come those struggles.
Non of that are in this storie.
And I'm concerned people in reviews think that way.
So warning for below:
Review contains mentions of physical, sexual and mental abuse. Alcolism and drug abuse.
The ML is straight up emotional abusive to everyone around him and doesn't mind to just physically assault people (and pianos). The author tried to give him a more sympathetic back ground story far too late in the story, but discovered that you don't have to flesh plotlines out, if you just give the character a character switch.
Which brings me on how he falls "in love" with the FL, which is not love for most of the story, but infatuation.
He hates her guts in the beginning (which is actually justified) but has sex with her a few times and suddenly he says he's in love, while never giving a real reason why he has fallen in love with her (he doesn't even give the cliché 'I love her because she's nice to me' line). He can give more reasons why he thinks baby trapping her is a good idea (which is rape), than reasons he loves her.
He knows nothing about her, which he recognises himself and results in big conflicts.
He also does nothing too learn anything about her. Everyone else around him has to spoon feed him information. The closest attempt he made to get to know her was giving her a new piano. After he broke hers during a jalousy tantrum, at a party that he was hosting, purely to out the FL's ex as being a rapist and revealing his victim got pregnant (and therefore shame the FL for loving a rapist), without any regard how this information would get the victim kicked out by her family (luckily she got saved by her boyfriend, before the ML could reveal the whole truth).
But don’t worry guys, he wants to change because he became infatuated with the FL. Not because he realised he's drugs and alcohism also destroying the other people in his life or his own. He doesn't change his behaviour towards others unless it makes him look good in the FL's eyes.
Which brings me to the FL. Is she any better? No.
In the beginning, the FL manipulates the ML in marrying her. But instead of becoming a well written, complicated character who you love for being manipulative, she became a blank slade. She has a default "medium nice" setting. And in an attempt the show character "growth", the author makes her sometimes say something assertive and then she changes back to her default state and does nothing.
The author also give no reason why she's so popular, beyond her being pretty. She's not as nice as the people around her claim nor do we see her do anything for them. She prostitutes her maid out, without the maid having any choice, to fuck her husband, because he made a cruel joke that he wanted that. Mind you, in this stage she still thinks he's having affairs. She had no reason to be certain he wouldn't do it.
We also don't get to learn anything about her, beyond that she likes to play the piano, read books, used to love her ex and her wanting a child (still doesn't excuses the baby trap attampt).
Oh and don't get me started on the pedophilia of multiple adult guys falling for a 16 year old.
Or the implied racist stereo types of an Arabic codes country.
And there's more, but I think this is an impression enough.
The writter maybe tried to write a story about overcoming addiction and finding love.
And while the destructive part of addiction is somewhat accurate, the healing part looks nothing like it is in real life and is pure power fantasy for people who hope to fix others in there lives.
There's nothing wrong with liking a power fantasy, but don’t confuse it with good representation of mental health.
