I love both first and second seasons, but have to admit that the second season is more flowing. The main leads are so cute! I ESPECIALLY JUST LOVE THE KISSING SCENES! THE MALE LEAD IS SO SO SO CUTE!!!! I love the apathetic, cold, capable look! I wish the ending was a little longer for both seasons. I am surprised this tittle is not rated higher! I love quantum physics aspect about time travels and parallel universe stuff. I totally LOL in a few scenes! I can't say it enough, but I love this series both season. I can not wait for the third one!!!

The both season are not long and dragged out like others. I wanted a longer ending. Just like other dramas, there are still some of the WTF moments but over all it is GREAT!!!

ACTING:

The acting is on point! I can't complain. The chemistry between main leads are awesome! Love it!!!

REWATCH:

It is the first series I can't wait to rewatch! I would totally rewatch the interaction between the main leads. They are super cute!!
