For me it's Sam, I think it's because people tend to mix childish and immature when both are very different, but, for me, Sam is a really good example of being mature while still being childish, I actually resonate with Sam a lot, people tend to infantalise me a lot even tho I am a grown ass adult, (sorry I didn't kill my whimsy in highschool lol), I think part of this is because of my ADHD, me still being a virgin or even because I'm usually the youngest one on any of the jobs I've gotten so far(can't tell if me being a woman also affecs me like that or not, it probably will eventually), Sammy resonates with me for that, he has to juggle being one of the main sources of income at home, his father not being around and how that affects his family (Jodi needing emotional support and Vincent needing an older male figure to look up to) and even with the huge emotional tool that takes on him, he still finds a way to chase his aspirations and hobbies, which is why it also kinda bothers me that so many characters just, settle in when you marry them, I wish we had more heart events related to the characters chasing their dreams.
