Awkward person needing internship advice

Next month we’re starting our summer analyst stint and I’m a bit worried how I’ll come across. I’m at sort of a fratty bank, but have been pretty nerdy my whole life. I’m not really into sports that much. I spend a lot of my time on YouTube watching videos about random history stuff or just videos on current events. Used to like video games but have really kind of dropped that since college. I’m a bit awkward in general but think I’m sort of a funny person. I’ve always been able to get along with people pretty well but I’ve just never really been that broey or cool. Not sure if I should just be the person I am or pretend to be a person I’m not. Not sure what is worse. Fits a big deal in my group specifically that’s why it’s been on my mind.
