first i would say this lives upon their name One and Only, the story is shown beautifully by the actors not just main couple but everyone did amazing, they express such emotions and i would say my every tear worth it because i never cried so hard for a drama.
i watched very late because i don't like watching sad endings but i have to watch it because i missed this so much, after 8 ep. i put this drama on hold because i get to know it has sad ending but recently i just saw a clip and i say that rather than ending focus on story development maybe there is rarely any other drama that can compare with this one oh right i would say TTEOTM can but not this much though their endings are almost like this but i would say One and Only is far more than that.
in this its feel like you are feeling the real emotions of them and your tears are automatically rolling down.
Ren Jialun and Bai Lu really did put lots of efforts and i have no words to describe this any further its just literally too good but it will make you cry more than you cried ever but just give it a go and you will find out the beauty of this drama ans ost.
THIS IS TRULY BEAUTY WITH BONES...
