Ok, I STAN THIS COUPLE, despite everything he was capable of being reasonable, mature, and hold his impulses well. He was worried about her being alone and sad and he didn't ask her if she was in love with him (it'd be normal from any other possessive character, but here he simply knew when to stop).
Idk how the author makes it but despite the dark vibe of the story, I can feel a pure and honest feeling here. Tnksm for your hard work guys!
Edit: 7 months later and sorry for tag u but you bring me memories of the "Archmage’s Daughter", that story was fantastic but suddenly I stopped seeing the story's translations. I do wonder if someone kept working on it )":
