Akatsuki no Yona. I think the love triangle of these three is similar to that of kagome,inuyasha, and kikyo. Suwon being the kikyo, hak is Kagome, and yona is inuyasha. I believe she will ultimately choose hak because they will have gone v through so much. And anyways no matter how much she loves suwon she is a girl with honor and can't be with him that way. Suwon will probably die when this series ends because the dude sports the Anime hairstyle of death.
