How will a (tall) French girl be perceived in Korea? Living and dating?

So I'm a French girl who's been living abroad for 5 years now. I am fluent in English and I also hold american citizenship but other than that, I was living in France before moving to the UK for uni.

Anyway, I've been teaching in Thailand for 2 years now and I will most likely be moving to Korea by December. I was never interested in korean culture before meeting koreans and it was not until I went there for a trip that I really made up my mind. I used to think Korea was only about K-pop and plastic surgery and never did I expect to fall for the language, the lifestyle, the food and the people :)I am fully aware that nowhere's perfect and I may be a little too excited but I am committed to move and teach there now.

I also have questions regarding dating as I met up with a friend in Seoul. We met for the first time in Thailand and he had invited me to come visit him a year ago. During the 4 times we saw each-other in Seoul, he was very complimentary, open-minded, caring and of course he insisted on paying for everything. He would also stand very close behind me as we walked together and he made sure I always went back home safe. I also met his friend and he told him I was "so cute, smart and nice" but other than that, he didn't try to initiate anything. He is my main contact and I think it's safe to say that we "clicked" but I was just wondering if he was simply "very nice" or if he felt something too.. Oh I'm 23 and he's 27, he says age doesn't matter (very unkorean :)
