<human>: Provide a brief overview of the text.

I met this girl while on an internship in Beijing, where both of us were there because of a study abroad college program.

We first met this January, and we would generally meet on the weekends since we were both free to explore the city (go to cool places, eat, sing KTV, chill). My impressions during those times of her were very positive. Her impression of me were both very good as well.

Last month, we both came back to the U.S. to continue our studies. We kept in touch, albeit much less since we've both been busy with school, as we both study different but difficult majors. Not much time to spend together. We've gone on informal "dates" together both alone and/or with friends.

I think I am a very charismatic guy towards girls, but lately, I feel like she's getting pretty close to me. And I don't know what this feeling is?! I'm feeling afraid to advance the relationship any further or take a risk or take it to the next level? As a result of this fear, I guess I have been acting a bit colder to her, to the point where she asked if I was ok, since I have been acting different from usual. She told me "I know we aren't close, but let me know if anything is bothering you and I can try to help."

I never realized I made it obvious. But yeah.. I'm actually not sure what's going on. She's a really cool girl. And I'm pretty sure she's hinted towards me so many times she likes me. But I am afraid to take it to the next level. What gives?
<bot>: Girl I met while on a study abroad has given me many hints that she likes me. I think I have some feelers to her too. But I am afraid to advance the relationship any further, and I don't know why?
