Well I'm not from South Korea nor lived there before but I believe it's similar to Japan. "Is it possible to live there being gay/lesbian if I didn't show TOO MUCH affection in public?" Yes. But pick a place like Seoul. People are more open-minded and there's definitely more diversity. "Is it hard to find friends?" I don't think there's an answer to this but hardER than U.S I guess. "I know that employers are even able to fire you after finding out about your sexuality." I don't know about Korea but it's illegal to fire someone because of their sexuality in Japan and I've never heard a single person getting fired for that. It depends on how you take it. Even in America people still judge you for being gay. Over all I imagine it's a little hard to be gay/lesbian in Korea or other Asian countries for that matter. And remember this is just my perspective and more importantly it's not America or Europe. It's a different culture so don't take it personally. Btw I have a friend who is gay and he seems to be doing alright so far. He's not hiding nor insecure about his sexuality.
