I watched this show because I'm a big fan of Lee Je Hoon. I was impressed with his performance in Signal and Move to Heaven. For me he's one of the hottest and cutest Korean actors and very talented too. In this drama he also performed very well although this drama is not his usual type.

Story wise: The show started well and made you wanted to watch more but as the show goes on, I found it's pretty depressing. I know this is not a common review. I didn't have a good mood watching the show. Although there are some very sweet cheesy scenes, the show focuses too much about their future death. I mean can we just focus and treasure the present? And if you already know that you will die on that specific day at that specific time, why don't you just stay at home? Why did you go out on the road? A lot of things can be avoided if they just communicate with each other. For me that makes the plot weak.
There is one unanswered question for me. How did So Joon and the ajusshi got the ability to travel to the future? How did they get selected but not Song Marin? Maybe I missed something?

The couple: they have some good chemistry there. It's not electrifying but the chemistry wasn't bad.

Characters: I couldn't say that I like Song Ma Rin. I think she sulks too much. Nothing really stands out from her personality. She sulks for days because So Joon keeps secrets from her but what do you expect when you marry the guy after 3 months? She did get better and became more understanding as the show went on but it's still annoying watching her sulk. Also, Shin Min A should practice her crying scenes. You know that she's trying to act when she cries, it's not natural.

Overall, I didn't think that i wasted my time (maybe because i love Lee Je Hoon too much) but I definitely won't rewatch. If you like time travelling this show is for you.
