Need romance help! Very specific situation! Life changing! Please at least check it out! Thank you so much!?

So, I'm 16 years old and I live in the LA area in California USA. I was using an online messaging app to talk to my friends who can't text. Now, this app allows access to games. I tried it out to kill time one night. When I was using it I met a girl. I'll be honest from the start I chose her because of her looks. And as I spoke to her, we got a long extremely well. Actually, (she knows this) she's exactly likening best friend. Now lol my best friend can't help me out, this is a me and her thing and I don't want him to know just yet.

Now... These are the pros and cons now that I think are equally important:

Pros:

1.)she seems to like talking to me

2.) I've said many things like "if you're ever in town, maybe we can go to their concert (her favorite bands) together. I'm not really a concert guy so it's the only reason I would go. (She isn't a concert person either)

3.) I asked if she's single, she said yes, I acted surprised. Then I said, "that means that you gotta make it easier for guys to make a move Hahaha, but just a little easier ;)."

4.) her response to that was playfully saying "you sound like you're speaking of your own feelings and experience" then I didn't reply on purpose but I read it just so she knows I saw it, then after a bit I said "LOL" and she said "what's so funny, Hun?"

5.) I played around a lot and I started talking pretend couple-ish too I think it added some humor to the mix

6.) she had me do a personnality test and we both were introverts and she sent a winky eye emoji

7.) when I described my best friend to her, I said that he is really nice and helpful and everything, but he's also flawed, and I think those flaws are what make him the ideal best friend, I said she's just like him so maybe she thinks that how I feel toward her.

8.) I'm making a mix for her with all her favorite bands songs "fallout boy" and she doesn't know it but I wanna make a dance video with my team to it to kind of impress her or please her or something.

9.) she likes history, and she said that I seem like the type of person who knows all about it

Might be pros, might be cons:

1.)when she asked if I was after her heart or whatever you wanna call it, I ended up saying "If things keep running smoothly and I end up going to Chicago you can bring that up again lol" and then I said "But for now lol o think we're in a nice enough spot, yea?:) 👍🏼?"

Then she said "yea sure man, whatever you say :)"

2.) after a little bit of talking pretend couple style, she said "I could keep going but I'm not gonna."

3.) I dunno if it matters, but she's half Korean half Swedish, I'm 1/4 Loren and 1/4 Swedish with Filipino.

Cons:

1.)she lives in Chicago, I don't mind, he'll I'll even move there for her or vise Versa in the future to stop long distance

2.) she is 20 years old, I dunno how she's feel (I'm ok with it, when I'm 21 she'll just be like 25, even parents are usually pretty far apart)

3.) she keeps bringing up this guy in Germany, he wouldn't reply and she said she's worried because he's been depressed lately, then later she sent me a picture and said "wouldn't you go homo over him lol?"

Keep in mind, her personality type is intj, mine is Infp-t. She said that everything about the description of her is true, except for that they're very intuitive and factual to the point of being egotistical and pretentious.

However, i might've seen little signs of those two, like egotistical. One time she told a joke and when I said good one, she said "lol yea sometimes I so funny"
