No, Idk, I think I'd be in awe or something. Idk, my younger bro is a gamer, and I only play otome or mobile games so I'd think it's only natural that he's good at all games lol.
Though unlike Jinsoo and Jina, our sibling relationship is much better.
Bruh I'd be so embarassed if my brother (who only plays mainstream video games) knew how to play my fav otome game better than me
