Omg I finally got that German woman's Instagram today. Do you feel it would be fair enough to ask her out for a coffee?

I already shared last week that I met this tall blonde German woman in this Cafe near UB City mall in our city Bangalore, India who was with her friend that day. Today I bumped into her again but she was alone. I initiated conversation with her and we both recognized each other and had an amazing conversation while walking next to each other. She is 21 and I am 24 so its perfect. She is a young professional now living in Bangalore for 2 months so far but she is saying she will most likely return back to Germany after 2-3 weeks. We had a long convo like how her work is going on and I also shared about my limbo phase of graduating MBA and searching for a job and she too understands how frustrating it is. She is taller than me too as I am 5'9-5'10(175-177 cm) and she is definitely 6 ft and it felt crazy walking next to a taller woman and talking. She is gorgeous and I think I got a bit of crush on her as well.

I eventually gathered my courage and politely asked for her Instagram and omg she shared her Insta ID. Like she asked my phone and typed her ID in my Instagram search pane and sent a follow request and then we said okay bye as she was heading to smoke somewhere and I was going for Church St. She didn't follow me back yet tho but if she does follow me back or if we meet again next week, can I ask her for a coffee? She is only here for 2-3 weeks so I definitely want to make the most out of it. It still feels like a dream tho.
