I find that the plot is unique even to time travel has been done countless times , there was something about his the story just really stuck out , i guess it was the mistereis taht never end.
I love the character development and countless plot twist ,i can see the who wrote this is very smart. The only where the drama fell through would be the female leads character it self like for real tho as much as i love Nikki (Cheng Jia Le) she was slow sometimes and kinda dumb also , but the romance and chemistry between the lead made it all worth it like I fucking ship them so bad and they hella cuteee I cant like .
It is adrama that catch your attencion and makes you want to know more. It is a simple drama with a lot of cute, drama and mystery.
You should try to watch. pleass try to support the femal charactre she is kind naive and child but sometimes can suprise
