Ooh! Yes! Thanks for the ask!
The first character I first fell in love with: Captain America :) Civil War was what really introduced me to the MCU (the only one I'd seen prior to that one was Guardians of the Galaxy...and I was so oblivious then that I didn't even know that was an MCU movie itself so really Civil War was my first), and I really liked Cap in that! Immediately after finishing, I borrowed 2012 Avengers from a friend and that was what sucked me in for real. Man, I fell in love with Steve Rogers right away. He's just such a good dude and such a strong leader and he cares so much about his team. Honestly Cap is the reason I stuck with the MCU all the way to Endgame. Heh, I guess I was with him til the end of the line. :]
The character I never expected to love as much as I do now: ✨XU SHANGQI.✨ Also, Scott Lang. I love Shang Chi so much and Ant Man is just so funny!
The character everyone else loves that I don’t: Iron Man. I don't understand why people like him so much but ehhh whatever.
The character I love that everyone else hates: Clint Barton! Okay I know there are a lot of people who like him, especially now that he has his own series, but I still believe Hawkeye is super underappreciated and deserves more. 💜
The character I used to love but don’t any longer: Thor. 😔 I don't like what they did to him in Endgame. I don't want to see where they go with him afterwards. Ragnarok is where the story ends for Thor in my head. I just don't think Endgame handled his arc well or lots of other arcs, for that matter. Cough cough Cap
The character I would totally smooch: Hmm...uh...maybe Loki, if I ever thought I had a chance with him. Idk, he seems kinda out of my league, you know? Lol
The character I’d want to be like: Captain America because he knows what he believes in and keeps fighting even when everyone else believes it's wrong. Clint Hawkeye because his life straight up sucks sometimes and he's so tired and so beat up and worn down but he finds the will to keep going every day not only for himself but also for his family. Scott Lang because he makes sure no matter how crazy life gets, it's still fun.
The character I’d slap: Thanos first. Maybe Loki if he was acting stupid or making questionable decisions or being a jerk to Thor. Probably Shang Chi's dad if I had the chance.
A pairing that I love: Star-Lord and Gamora. Yes, I know. Yes, it still hurts. Don't remind me. That never happened. I erased it from my mind.
A pairing that I despise: This would infuriate a lot of people lol but...Tom Holland Spidey and MJ. Yeah. I don't "despise" it but I'm just not a fan. ¯\_(ツ)_/¯
