Mentally speaking, he is older than the king??? but then ig the king got older while he didn't reincarnate so they're the same age????? GUESS IM THE ONE GOING THROUGH CRISIS

further chaps, abel is still mentally 18 yrs old and compare to karas who has more experience further, abel is much innocent at some point. (spoiler) so there will be a situation where both of them dont know what they're doing(perv scene) and then after that karas will "learn a lot" from his knights lol, but he will get a hard time to convince abel as abel still think he shouldnt feel and do that way to his highness. so, we'll see a lot of scenes where abel don't know and understand what he's feeling, while karas are already sure of what he feel towards abel. (in terms of mentality, its the other way around)

here's the link. tho i forgot which chapter is the last chap. https://lilyonthevalley.com/story/rgs/
but he's actually a namer so... ig it'll be romantic if he starts to like him without knowing abt the name
