Letting someone down in Korean This is a long question...but basically I met a guy 소개팅 and we went on two dates. I think it would be best to tell him I'm not interested right away, but I'm not sure how to say it nicely. I want to say "I had a great time with you and I'm so glad I met you, but I just don't see a relationship with you." I want to express that he's a nice guy and thank you for everything...basically I want to let him down nicely. Can you help me? Thanks~~
