Story begins with the flash back .Love story of grandma who went to city along with her foster parent to do theater there by the time she fall in love with a man named Xu Xing Cheng who was a very kind doctor because of his kindness she fall in love with him . Another man named Luo Fu Shen who was Xu Xing's childhood friend and a police man fall in love with her ,so basically a love triangle and it was not easy going love story. When Xu Xing proposed her and she accepted him then twist of the story had started . Due to a reason she broke up with him and he crazily wanted her but all the time she avoided him and try to stay away for him . As time passes she and Luo Fu started came near as a friend ,their relationship was cleaned and he misunderstood them and change into evil person. So basically writer change a kind person into a evil person so we did not felt bad for love triangle when both the persons feeling was genuine. I would not unfold the whole story as it would spoil the mood.
The girl who was telling a story of grandma was dobbleganger of grandmother's face and to whom she was telling a story was dobbleganger of Luo Fu Sheng face so we assumed that they were recarnated .
And his present love story was his finacee already dead and for many years he didn't love any other girl and he confused that he loved her or not because his fiancee exact looked like her and he didn't hurt her so he left her.
Starting flashback story was good and rest was just okay.
