I think not. He's taking advantage of her vulnerability, yes but she also has a strong character (and violent tendencies). Take the cousin for example. The moment she knew what exactly the cousin was doing to her brother, she beat him up + it's not ending there bc she went to his funeral.
So from that I think it's safe to say she will go as far as wanting to kill Inseop with rage
I really hope so :( I just have a hunch that she won't believe he's the murderer until later in the story. Idk I thought she would become more involved w him and keep swaying between him and the detective (otherwise the detective's role would become sort of redundant, or that's at least how I view it)

Wtf it'll be soooo frustrating if they end up together >:
