J-dramas are often built on a foundation of quirky characters and outlandish premises. They don't all work but when it does, it can turn up some memorable and unique dramas.

Unfortunately, this show seems to have missed the memo and what we got is a nice romance drama but there is nothing fresh or unique about it.

The biggest selling point of this show is the life goal of the FL. She has set her mind on when she will be married and when she will have kids. Everything should be done and dusted by the time she turn 30. However, life has other ideas and she turned 29 and has little prospect of marriage let alone 1.3 kids.

In stepped a "stranger" who promised to marry her on the day of her 30th birthday. That is a chivalrous move but it would have worked better if it was a written short story. In this case, it is stretched to 8x20ish mins episodes. It is still watchable as a run of the mill office romance but little else. 

There are swoon-y moments and a reasonable amount of skinship. It is nice to watch the ML trying to woo the FL and deliver a promise made on a whim. It helps that he has a crush on the FL but there is a lot of pushbacks from the FL initially. She is confused about the ML's motivation and whether it was all a joke.

As a relatively short dramas, it is sweet/nice/decent enough and an easy binge. It is perfectly suitable for that but it would not be my first choice and it has minimal rewatch value. Peace out.
