He's the one ML everyone can agree is down to the core fucked up and everyone wishes he never get together with Dan.
It really takes a special person to make the main character of your story so unlikeable. Also even if they got together, no matter how many times he apologised or try to pay back for his mistakes, he's highkey abusive and a narcissist (and a rapist).
I'm reading solely out of spite and waiting for his downfall. Losing to Baek Jumin isn't enough.
