[Western Crossover] + A Natural Belonging

So, I transmigrated... into the MCU. WHAT?! I'm just an ordinary high school student studying for exams. Why do I have to save the world? And what's this about a seventh Infinity Stone?! As a Marvel fan, how have I never heard of it? I want to go home! Why do I have to go through all this? If anyone in this world can answer me, please tell me: where do I belong? Suffering turned me into a believer.

Steve: Amber, I'll always protect you.

Stephen: Tsk, I don't want to see you looking this awful again.

Black Widow: Girl, get a clue!

Professor X: You are that starry sky, Amber.

Bucky: I know you, Amber.

Iron Man: ...What are we going to do with such a ditz?

Spider-Man: Yeah, Amber is one of the most important people in my life!

The Ancient One: Want some tea, little Amber?

Is the pairing with Captain America? Maybe? No guarantees that other pairings won't show up as the story goes on. I'm just writing this for fun, to make myself happy. This is my first time writing, so I'll try my best to keep the characters in character. The heroine's powers might not appear until later.

P.S. I'll try not to make the heroine too overpowered.

P.P.S. It seems like she's already overpowered??

P.P.P.S. Oh well, so what if she is! This is me fulfilling a dream. Captain America: Civil War and Avengers: Infinity War were just so heartbreaking. I hope I can give them a better ending in my story... I'll try to post more at a time from now on. College really is stressful, and there's so much more to do, so I won't abandon this story! I won't abandon this story! I won't abandon this story! The important things must be said three times! (Updates may be slow.)
