I am a sucker for time slip tropes so as soon as this finished airing and after checking that the ending is probably to my liking, I went for it. I won't lie to you, I binged it in three days but eventually I did not like it so much. There are a lot of issues I have with it.

The story is quite straightforward: two people leading boring unhappy lives are given a chance for a redo of the last ten years. How are they going to deal with the knowledge? Are they going to use it to correct past errors? Spoiler alert: they do of course! Otherwise what's the point of this drama?!? And so the doormat FL stands up for herself and comes up victorious!

The drama is fun to watch. There are a few tropes that do not go the usual revenge, makjang mode so that was rather refreshing. The chaebol grandfather and his lawyer are not the usual evil heads out to ruin our FL. They turn out to be kind and reasonable. But they could not do away with this cliché completely with the appearance with the psycho ex girlfriend. Mostly, the support characters were the usual clichés: jealous, greedy, bullying... And the glasses issue: ugly with them, drop dead gorgeous without them. We are still doing that? Of course they are kitted out with the most ugly and the least becoming models of glasses otherwise, the change is not obvious enough!

The change in the main characters' personalities is just as obvious: they both went from doormats to smart people who stand up for themselves and won't be beaten down. And even though the FL becomes cocky and looses her newly acquired smarts towards the ending, making idiotic mistakes, she comes back rather quickly!

The main support characters were more interesting: the joyful sister, the unassuming boss, the regretful cook (with a beautiful smile) and the quiet but powerful lawyer.

The first major issue I have with the plot is the time travel aspect: it was never explained who the mysterious taxi driver was? Are there any other cases like theirs? How are they chosen? Probably, the person needs to hit rock bottom and die in order to be offered a reboot! What is the significance of the heart? Was the time travel offered by her dead father (who was the taxi driver for ML)? I guess, one should not think too much about the logic when talking about time manipulation! I hoped to get an even cursory explanation at the end. Nothing! I was also surprised that the leads never wondered about the hows and the whys of their reboot! The aspect of the reboot I liked was the way their fate was transferred onto others and how they fought to save their friends from that fate!

The second major issue I have is the cast: Park Min Young looks too sleek and smooth to be true. People say she abuses of plastic surgery. I hope not but she has changed a lot over years and here she looks so artificial and even older than her age. Her face is pretty much expressionless: she can smile and cry but nothing else moves. Na In Woo looks like a very tall kid next to her. There is supposed to be an age gap (3-4 years tops!) between them but it looks much more!

Everything considered, this is a fun and a very forgettable watch. Things happened, but I cannot think of much now and I actually wonder what did they fill these 16h with? It went by and it was not too boring, so I guess something must have happened! This was Park Min Young's show from the first to the last minute. Unfortunately! LOL
