Overall: although this has some of the same characters and the overarching plot is similar, it's best to think of this as totally separate from Ossan's Love 2018 series. I laughed soooo hard at the ping pong and sumo scenes and appreciated the lack of the ex-wife character. There are several love triangles, rectangles? but it's really difficult to predict the ending. Watched on Viki.

Note with franchise:
Ossan's Love special 50 minutes long Japan 2016 (I haven't watched this but it's like a shorter movie)
Ossan's Love series Japan 2018 (expanded from the special), on Viki
Ossan's Love: Love or Dead movie 2019 (a continuation of the series and best to watch after the series)
Ossan's Love in the Sky series Japan 2019 (this is basically an alternate universe with differences in plot and characters), on Viki
Ossan's Love series Hong Kong 2021 (a retelling of Ossan's Love), on Viu in some countries

Content Warnings: manhandling, non con touching and kiss

What I Liked
- there were some real crack comedy moments
- also heartfelt moments
- I appreciated that characters communicated with each other (with some missteps lol)
- episode titles were cleverly integrated

Room For Improvement
- the intro and some of the editing was too frantic
- Haruta's character has a type of over acting, it's not really my thing but I have become used to it
- love triangles/rectangles are not something that I enjoy
- it did feel rushed especially towards the end, I think this was originally supposed to be a longer series
