The diff between the two bros is older one is a fucking asshole and a sextuality harassing scumbag (don't forget the first chapters where he almost forced himself onto the uke even though uke said no he still was groping and kissing him).
Younger bro is soooo adorable like you just want to gobble him up for the sugar rush sweetness. My Boi asked for ukes consent and even apologized for being clumsy and rough.
Boy you better back the fuck off you creepy blonde
