So based on Iseon's behavior all throughout the story + his flashbacks and explanation, he appears to be aromantic(?) I don't think he's that much of a bad guy since he genuinely wants Yumin to be happy regardless of whether she's in a another relationship or not. At the same time, it's also seen in some panels where he has this moment of gloominess when he slowly starts to realize that she really does like someone new. What are those feelings he's having when he's not attracted to her, then? Is it really jealousy or something else?
