The Japanese title sounded familiar, so I looked it up and realized that I read the manga. This manga is from 2013, so I had to go back and read it. They should have stuck more closely to the source material. I think the actors were good,.

There was too much filler to stretch the series and I wish they would have stuck closer to the manga.

****Spoilers****
1. The exes. No Mizuki, and the ex-wife is just mentioned in passing in the manga. A weakness of the series is, more lovey-dovey time was spent between Mizuki and Sakae, than Soga and Sakae in the series, did not happen in the manga.
2. In the manga, Soga reveals he is divorced right away.
3. In the manga, Soga is from Shikoku, not Tokyo, so no return to Tokyo.
4. In the manga no break-up, no LDR.
5. In manga, no filler such as the birthday party plans, the meddling co-workers.
6. Part 1 of the manga is Sakae x Soga, but Part 2 is about Kaname and and a salaryman, who is a regular and Tamae, is from Tokyo and hates vegetables.
