If you think one and only is slow, do not watch this one! it's not a continuation of one and only. It's just about reincarnation and finding true love in another lifetime. Other than that, there is no connection whatsoever. The casts (other than the main ones) are also different from one and only. The era is many gazilion years after one and only. So if you would like to skip this one, you're not missing anything.

This has got to be the slowest drama that I've ever watched. I watched it in 1.5x speed and it still feels slow. In this one, Allen Ren's character is so timid and cowardice that i want to smack him in the head sometimes. Even after they're married, they don't act like a married couple - this i don't get at all. And the whole relationship is so unreal, especially since it's set in the modern period. There is very minimal conflict and until now i don't get who the antagonistic character is.

I think this is made especially for those people who hate the sad ending in One and Only, and would like to see the couple get together, which i totally understand. But this seems forced to me.

One and Only is so much better and in my opinion, you can watch it as a stand alone. I'm not one who hates sad ending. So it's fine for me. Sad ending is preferable than any open ending
