Ermm hi :) well the only thing i suggest is 당신 be yourself, girls like that. We don't want to go out with a fake. Also you're only 17, you're still young, it will take some time to find "the one" trust me, 당신 have your whole life ahead of you. Also if you're really desperate 사랑 won't come, 당신 don't find 사랑 it finds you, and there are plenty of girls out there who would 사랑 to go out with 당신 i bet :)
HEY! I just became a 팬 of you! :P Sorry your havin trouble with finding her? If I were 당신 I'd just be myself and not go chasing after love. Let it come to you. 사랑 like that is always the best. :)
