The moment she left the train, all logic lost.

The story started out fun & interesting, so I thought it was going to be as strong as the drama "Extraordinary you."
Favorite aspects of this drama:
-ML Byeon Woo Seok did an amazing job and surprised me with that singing voice.
-FL Kim Hye Yoon always does a great job with these kinds of roles.
-The pairing is super cute, great chemistry

Not so great....
-Weak supporting characters & stories.
-Pacing started to slow down midway, and the constant crying scenes got repetitive. Nowadays the most annoying trend is for dramas to replay scenes that JUST happened 10 seconds ago as if viewers need a reminder.
-Ep 12 on the script went south as the FL made illogical decisions. And if you just go with those decisions she comes back to current time, shouldn't she try to find the SAME one-dimensional suspect? Girl has a cop friend/2wk ex/15 yrs 2nd lead she can ask..... Running away from the killer situation is not really fixing the source of the problem.

Downfall of many fluffy romances with strong beginning is the sloppy writing at the end.
