And am too scared to try it. Can someone give me a quick summary (I don't mind spoilers) so that I can decide whether or not to read it?

Long story short, the Uke being forcefully imprinted by another Alpha/male lead, seme get closer in the name of remove the imprint and eventfully get the uke pregnant in the process. the seme is trash in both lives (first and second timeline) He deceived the uke, played with his feelings, and used the prince (Uke) as a tool for his revenge. A lot of novel readers said that he don't deserve the uke.
Another "Spoil" or ranting anyway,
(I typed it a long time ago and too lazy to edit it, I will just copy &paste it here)
Why would he (the ML) help someone he's just met? Not just helping — it's like he goes beyond that without reason. Also, he's hiding a lot from the MC and never once shows his real thoughts or feelings towards them. It feels like blind faith without reason — kinda fishy, you know?
And then there's the omega scent that always lingers on his clothes. (Okay, we know from the spoilers that he didn’t really cheat, but still — it’s too much. It’s offensive when your partner doesn’t respect you enough to be clear and honest.)
And the sh*ttiest part of all, the thing that confirmed all my doubts (even before reading the spoilers): why the hell would he continue the intercourse even when his partner was bleeding? And then the one time he thought it was fine to let his partner sleep with someone else just to undo the mark — what the hell kind of logic is that?! Even if it’s the fastest way, no sane person would accept that for their partner. Usually, it’s the opposite unless you would do that to your enemy or someone doesn't really matter to you.
Sorry, I kinda couldn't hold it in — it was just too much. And also the MC — he's always hitting the ML. What the hell is this relationship? I really hope they change their behavior and choices in the second timeline.

Like he straight up felt psycho despite not doing much (ohhh wait, he ran over the MCs mom just so they could meet ahaha), so when I saw him getting a side story I immediately stopped reading and decided to wait until I saw the comments when it ended.
Glad to say, I wasn't wrong. I don't know what he did, but based on the comments, I'm NOT going to fk around and find out ╮( ̄▽ ̄)╭

That in order to make your audience ROOT for a flawed , messed up, toxic character, you have to make sure he isn't absolutely IRREDEEMABLE!!!
Stuff like Cheating, domestic violence, killing family members, completely destroys the ML's image and you're better off just killing him atp.
Confinement, drugging, rape, sexual abuse, apathy, betrayal of trust etc are themes that with the right character development are often forgiven by readers (not that it's right whatsoever, but you come to expect them from stories like these).
But this one?! Moyoung got his memories back first alongwith his present memories and STILL didn't think he did anything wrong. Like Mooyoung can never come back from all that shit bro.
Made us hate the ML for nothing
