He wouldn't even wait 6 weeks to fuck his wife post partum. The man got stabbed and showed you a place that's emotionally important to him, and you can only think with your dick? Goddammit, at least show some character depth-

Possible novel spoilers:
Yup, Jay is a sociopath (or maybe psychopath). His mom always wanted him to feel something and would always show him dad stuff hoping to elicit some kind of reaction but Jay was unmoved. The reason why he was so attracted to Yoohan was because the first time they slept together was the first and only time Jay felt “sadness” and he was curious about that unknown feeling. As for why he’s demanding sexual from an injured Yoohan? That’s Jay through and through. He’s mad that Yoohan got himself injured and he’s always used sex as a means to get Yoohan to feel anything so it’s not really out of character for him.

Sounds so fucking hellish. I have knee pain- not as bad as anybody with serious issues, but it's a constant presence. I remember a time when I'd think I'll go out for a walk, and just the thought of it would start twisting up my knee and I'd give up. I'd pushed too far on it before, so my body would give me this reminder before every activity. Some days after climbing stairs, especially if I'm not wearing my knee brace, my leg gets jammed up and I can feel pain even when there isn't any pain. I don't even know how to explain it.
I'm glad they portrayed it so well.
Someone mentioned in the comments earlier that the personality at night is still his highness, just without inhibitions.
My theory is that he's the literal gate to a demon. I remember in the Kane Chronicles by Rick Riodran, Gods lived within mortals and sswitched places or took over when necessary
Foe one character, a God and human even chose to essentially combine. Is that not the case here?
Yeah, I don't agree with the "night time prince is still the prince, just unhindered" theory people were trying to push.
It's moreso like a version of him that is warped and controlled by the demons trying to pass through him via the gate. He obviously cares for his people and those around him. It's why he does his best to keep himself locked up at night away from everyone else.
The only reason why the prince himself believes that the night version is still him is due to everyone spreading rumors about him going insane. It's just his spirit, body and mind being distorted by demonic energies causing him to be more unhinged. It's not like he's a psychotic rapist that beats the shit out of people like a sadistic beast.
Oh? That’s what I’m thinking all this time
Do people think he exchanged body with demon or what at night?
The people in the story that don't know he was cursed just think he's ill or going insane.
What's really happening tho is that the demon gate is opening wider each night which is causing his spirit and mind to become warped. It's literally eating away at his soul every night. It's not really him nor is it some sort of hidden version of himself like readers keep implying. We know this 'cause during his moments of clarity at night he regains some control of himself even if it's not enough to stop himself completely.
The same thing is sorta happening with Myungha too. The hex on his back is causing him to have uncontrollable fits at night. Some nights it's just a fever and others have him actively seeking out the prince even if he doesn't understand why.
It's best to see it as a form of possession rather than these characters just basically having a split personality lol
