i think my favourite member is felix, he seems like a fun person to be around and i love his voice. also i found out he plays genshin impact (or at least used to) and we had nearly the exact same team so that was cool
He sure does love video games. He's the sunshine of the group, the members really adore him and love him and so do stay
he's just seems like a very genuine person and does his best to make others happy (which is why they call him sunshine felix)
he also loves cuddling the members, you can always find him holding on to one of the members or showing physical affection

even if he isn't your bias, he's still your bias
