Hey guys, I just couldn't help but post this since I've no idea what to do in this situation, it almost looks impossible.
But ye, I'm taking a language class in a foreign country and there is this Japanese chick in my class, we've been together in this class for two months now.
See has shown me some really strong IOI's(her girlfriends smiling and pointing at me when they see me, repeating my name and so on) but because of language barriers I've never been able to do anything about it and now at this point we rarely even talk because there is just nothing to say in a group anymore. A thing that makes things even more difficult is that when we started there where only 2 Japanese ppl in our group and the other being a guy and a good mate of mine, but now they are 4, and as everybody knows 3+ people becomes a group. So now I have virtually no chance of isolating her without letting the whole class now, which is bad since I've to spend the whole winter with them. I've texted her occasionally and she is always happy to get them but now since we barely talk I've to stop that too so it won't become creepy.
My best chance I got a not long ago when I met her in a club and we starting dancing, but I was afraid to escalate and when she finally did an AFC was getting pretty aggressive with another friend of mine on the floor so I had to go and help her out, after that she left.

Any ideas on what to do? Except for hoping to run on her in the streets or in a club(which she never goes to unless in a group with japanese people anyways).

Grow some balls and talk to the girl. The sky's the limit.
