TIFU by missing out chances multiple times and ultimately fumbling a chance to connect with a stranger

Context: I come from a middle class family in a poor country, so I have never really travelled outside my country. I also haven't had that much social interaction since the pandemic, and I rarely go out or encountered strangers since then. Though, even coming from a country with English as its second language, I am fluent in writing but not in speaking (More on confidence and getting used to speaking, than having poor ability for it). So basically, I'm broke, no recent social interaction, and has no practice of english speaking. These are information that's important in my story. So here goes:

For the last few weeks, I had the opportunity to go on a trip to Japan. And one of my goals for this trip is to connect with a stranger, you know, authentic human connection. I have always yearned for connecting internationally with people outside my culture because I was an internet kid, I have always fancied the differences people have and have always desired to also connect with other people. So I thought, this is the stage for it, the international stage!! But I guess not having to interact with others, especially not on your language, makes your physical body not comfortable doing it. Because I can't really talk even if I wanted to. So days passed on the trip where I find someone interesting, and not have the push to talk to them.

And now here comes the day where I met someone, let's call her Russian (Not her real name, but I have learned she is russian). So, that day, I am going to the Kyoto International Manga Museum. It has tons of manga to look into (can't really read them since all of them are in Japanese) but it's fun to look at those you know. So there's this girl that seems interesting because her fit is pretty cool. And I saw her looking up something on the information screen where you can search up mangas and see where it's located or if it is available there. Then and there, I already know that I want to talk to her, but I can't do it. I am overthinking things. What should I say? Should I say something? Would it be weird? Can I word it properly? All those things. So I just stood around near her, and proceeded to just look at a manga I really like to make use of my time.

And now here comes the first chance I missed out on. She approached me!! She asked if I could speak Japanese (which I can't) so I just waved no, which you know is bad because I can't even speak a one-syllable answer of a "No"??? We just smiled at each other and she proceeded to go down the floors (we were on the 3rd floor which is the top floor of the museum) and so I went to the screen to try and look up the book she was looking for (I saw the title of the book she was looking for when I noticed her the first time.) Look, I don't know how to speak Japanese, but I know a few characters and I discovered that I COULDVE HELPED HER because I found what she was looking for (It was on the first floor). I should've asked her if she needed help, instead of just waving her off. That's the first chance I missed out on.

So then I proceeded to look for her since I can help her now, but I was too late since when I got down, she was already reading it BUT I kinda spoke so I guess that's a win. I said "Oh did you find it?" and she just answered yes and smiled. After that, I was already embarrassed so I didn't try again, though we bumped into each other a couple more times, and started smiling at each other every time it happens again. That's when I felt like I really needed to talk to her, but I also couldn't get a word out so I also am kinda giving up trying.

And then the climax of the story happened. So in the museum, there's a large room of a timeline of the mangas that are made that year. I went there to just read One Piece, and headed over at that time. In that room, there are chairs that are available for you to sit on and read. So I am picking up a volume when suddenly, as I stood up, she was beside me standing there and looking for her manga. I just greeted her with a shocked sound like "Oh!" and smiled at her, and she smiled back. With no hope of talking to her, I just sat down on a chair and just tried reading my way through my regret and anxiety. When all of a sudden, SHE SAT NEXT TO ME, of all the available chairs. At this point, I actually felt the tiny bit of connection we have after bumping into each other and greeting each other several times so the courage to talk is slowly getting back up. Though, I apparently can't still do it. Because this is the 2nd chance I missed out on: SHE LITERALLY SAT NEXT TO ME. All I did was look at her direction because I can't get a word out. There's times where she looks at me and laughingly ask "What?" and I just say "Nothing." That's so bad!! I just can't physically do it! I mean, she laughs after so it's more of a funny awkward, not weird awkard... yet.

And now the 3rd and big chance, I didn't miss out on, because it's literally handed over to me. And yet I messed it up. So I just looked at the panels in the manga I have on my hand, and she just took pictures of the panels she had, and when she was done, she looked at mine and said, "Oh One Piece?". She initiated the conversation!! It's spoon-feeding at this point. She's literally talking to me, which I should've initiated hours ago. So we talked, she said she doesn't read it but her friends does. I asked about hers and we also talked about the one she was looking for, then we asked for each other's names, I asked her where she was from and she answered. And now, here is the biggest f*ck up. I asked her if she was alone in this trip... "Oh did you come here alone?" to be precise... After I spoke that question out, I understood the f*ck up I just made. You just don't ask that... as a man... to a woman... She just replied (in a jokingly tone, but surely she meant it to be awkward) "Why are you asking me that?" with an eyebrow raise. I just said "Oh, sorry..." after realizing it. I've never felt the air change that quick. The conversation got awkward, and I can't talk to save the conversation. I couldn't save it. I mean, in my defense, it's pretty normal (idk if it's the same with others) to ask along the lines of "Oh so you're solo on this trip" or something along that thought. That's my thought process on asking that, but I worded it poorly, and I clearly understand her reaction.

After that, I can't really think properly and the best thing I could think of is get a paper and write her a quick note because I CANT PHYSICALLY HANDLE THE SITUATION. I just wrote a quick apology, I said I wanted to be friends, and left her my IG if she wants to still be my friend because that's the only thing I can think of. I awkwardly, without saying a word, handed her the note. Yes, the execution is really bad. I didn't even say a word!!! I don't even know if she read it.

Ever since that day, there's not a day on that trip that I hope to see her again so I can at least try to talk to her again and clear things up. To this day, I still regret the things I did and did not do that day.

I guess the very least I can take this as is experience, because I clearly need it. And I don't know if it's alright to try and look for her, but I guess it's really hard since I only know:
-Her name
-She's from Russia
-She was in Kyoto around mid-April
-She likes Flowers of Evil (Manga she likes) and Junji Ito mangas
-Her friends like One Piece.
So I guess if you know her, maybe you can help me. Maybe we can't try and be friends anymore but at the very least, I can apologize or share my perspective.

TL;DR: I met a girl, I couldn't talk to her, she gave me multiple chances to connect with her, we talked, I asked her a weird question to ask, ultimately killing the vibe and overall chance.
