I wouldn't say this is a masterpiece but it definitely hooks you right away!
I just felt like the mc's turn to a villain was kind of forced and he does not have much character development other than becoming a villain.
His justification for his actions towards his victims were all based on those who are a problem to the FL which I thought was weird since he barely knows her. I personally thought this was a plot hole just because they didnt really develop their relationship much before that. They're only sticking together because they are accomplices.
However, I do like that it has an unpredictable plot with keeps me on the edge
