This drama deserve some higher rating 8.4 is good but this deserve more, a well written drama every character have there value even there is some annoying character but they have also there reason unlike other drama's.
After is amazing performance in Empress KI(2013), this man he hell bent on taking only flop scripts
You have some personal problems with ji chang wook, if your favourite is unemployed then focus on yourself don't go here & there to hate other's people, live a good life go outside your home and touch some grass . Don't live a missrable life without happiness
Revenge, RomCom, time travel, fantasy in all these thing's this one standout the most purely a heartwarming melo romance drama.
Hope rating increase this deserve higher rating's
For me 10/10
