The author tries to make the mc look cool but it just makes it extremely cringe. "Omg look how cold he looks" "wow he seems so aloof and cool" like no tf?
author u sud tone down on how much u make mc look cool, maybe include little different phrases from different characters perspective. and hopefully there's no romance between these siblings even if they r not blood related, wud be an actual character development if he take she role of a caring brother form thus uncaring, walking nuke
