Didn't it ever cross your mind that love was never logical or that no one can control who they love?
Let's not cross out the possibility of Stockholm syndrome coated in sugar, because many of authors love to romanticise rape and excuse abusers.
Raon deserves happiness but so does ML and MC. After everything you can easily see what is happening within each character's heart and mind.
Not that I'm saying black flags get to be fixed but shesh MC soul was bonded with ML and as much as I wished MC to live a safe and happy life with Raon I know he will be struggling but happy with the Emperor.
Alas what an ending it has become...

OH MY GOD. so tired of this trope to leave the green flag to be with the BLACK flag of a man. Roha is acting like a bitch atp. All that humiliation just to run back to him tsk tsk. Raon deserves better
