It's a good idea to refer back to something you were previously talking about, something fun... something funny you both share, inside jokes are great! It will get her back to the right mindset. If you have given her a nickname make sure you use that too.
She gave you a definite IOI, so I'm sure she's interested in meeting up. You can go ahead and suggest hanging out right away or wait a till some fun texting's been going on.
But NEVER EVER tease ppl who are just studying a foreign language that's just rude. Helping her improve could be fun though and it gives you chance to use kinos a lot.
I remember some years ago a girl emailed me like "hey, long time no see, here is my number... we could have a beer sometime". We met at a bar and I fucked her in a toilet cabin there... those girls and their messages
