Ignore the spoilers he's not bad he never does anything bad to the FL, he's just doubtful he thinks she's like her father on all accounts he saved her, never abuses her he just provokes her, she should be dead and if anyone knew she was alive she'll probably be killed, MLs trauma is also portrayed well here he's constantly conflicted whether to belive the FL but still sees his parents being killed everytime he looks at her and thinks it's only a matter of time before she becomes just like her father, he becomes obsessive but it's still not a dark novel it gets fluffy the second half.

I'm giving this a chance because despite the plot being a very basic misunderstanding trope, that I've seen thousands of times, the male lead (I assume he's the male lead) doesn't seem to be super cruel or evil and fl seems very resilient and kind, which is pretty rare with this trope
but just after reading this much something tells me the betrayal and misunderstanding between these two is gonna be something that could easily be fixed if they just communicated with eachother..
