honestly i have a small tiny theory that the 2nd brother is the guy who took MC’s aunt captive and threatened to kill MC, just because even tho we didn’t see his full face in the family pic, the back of his head kinda looked like him. and not to mention, his shit personality would make the fact that he’s disliked by his whole family make sense, but i digress.
i see where ur coming from but the ages wouldn't make sense and we saw what the 2nd brother looks like as a baby an that kinapper dude looks different and more synonymous with a demon. Not to mention i dont think his personality is whats lacking, I thought he wanted to move to a diff planet but the mom hates that planet for some reason and flipped out when ML suggested moving there with mc

im so curious about their 2nd brother. Like i get they r upset he moved out but they r such a loving family no way they would just make him a forgotten topic :0 also i thought 2nd bro was adopted cause when we did see bits of him he had black hair but i now see that came from his grandfather
