Many MLs and WLs live in the same building and same level of my unit also. I've read this thread for long and thought I should share my experince or not.
I think your case is look like my case, I met a K-girl at the shop in newtown. And I met her again at the building, I was a bit surprised and excited
I remember the first time that I met her at lobby, that late night I couldn't sleep and came down to smoke, and I had a cigarette in front of the building, she looked like a normal girl (I hadn't seen MLs or WLs outisde their shop before) just came from taxi and asked me "Can I borrow your lighter?". I remembered her but I thought she couldn't remeber me.
After that time when I couldn't sleep as insomnia, I took my laptop to lobby and wished "I wanna see her again tonight". Many times I was lucky and talked to her at lobby until morning. I talked to her a lot, except how about her job. If I don't know what she do, I might fall in live with her. But I realize I was in the real world.
Then I went to her shop again and I saw her in line up...

I chose her and got unforgetable session

Just talked for 30 mins no shower, no service, nothing !!! ... She was very upset that she met me there and thought I was a stoker!, and told me "don't snoop her private life and her job again!" I tried to explain I'd met her before I met her at the building but she didn't want to listen!
On that night I waited her at the lobby til morning, I thought I shouldn't talk to her again, during that time I met her walked from a car, this time she wore the normal clothes as everytime I met her here. I explained everything to her again, she accepted my reason, But she told me "she doesn't want anyone know what is her job, because this is her private life, she wanna be a girl!" and asked me "don't go to that shop again, if I wanna be her friend!" because she couldn't aceppt if she has to work for her friend!.
Now she went back to Korea alrady and she's still my friend.
Anyway, You are so lucky. Enjoy your way
