yes, very good idea, >>15.
That is, if you want to make the total creep act.

The relation you are currently in with her, is one of her servicing you (teaching you). As far as I know, also from some experience, Japanese will take this servicing very far, leading them to be very very nice to you. That's the business they are in after all: If they are rude to you, you might switch class, and they have less income --> so, better be nice

Consider that in your pursuit of romance with this lady.
