Not really, Demon king never had that idea in his head and only thought of him as a younger brother. It wasn't only until he was forced to think about him as a spouse, did his feelings shift. Marriage was far from his mind. And it looks like he was unsure about the whole situation, but he was wondering over by ML. The ml is the one that kept pressuring the marriage concept. Even everyone around him mentioned how he's more like a little brother.
GOD, yall love to mis use that word so much, shut up
Not to mention the whole child marriage thingplot would’ve been better if they had just met at a normal fucking age and not when the dude was a squirt
Wouldn’t be as bad if it wasn’t for the fact that it’s basically grooming.
