Everyone should really stop blaming just Minjae, blame Hyera too, blame them both!
Hyera is the root of all of this, she's the one who started all of this just for her own entertainment and satisfaction but now that things don't go her way explains everything that's happened and happening right now. And Minjae is just her séx slave who will do anything just for Hyera's pússy just like what @yoontoyourseeun said.
