It's not an open ending nor a cliff hanging ending, instead the director and the writer did not give an ending at all.
I'm watching every episode genuinely without skips because I don't want to miss a part of it even the dialogues but eventually got slightly dissapointed by the ending.
Everything about the drama is good, the casting, the theme song, even the story is good, only the ending is unacceptable (unacceptable than the princess agent's ending).
Could it be that rocky really set new path and destiny as what his master's wish for him? That's why there's no ending at all. Even so, the director should give at least a single hint for the ending.
Feng Ling, I'm deeply attached to you right now even while writing this review my tears keep falling. You have suffered so much but you still choose to be happy for him. You sacrificed so much for everyone not just for rocky. Feng Ling, may you have a better and joyful life in your next life, my sweetest girl. Byebye.
