This review is based solely on the drama, as I never read the manga or seen any anime of it. But some of Sumire’s actions screamed manga moment, lol.

LIKES:
Writing:
The various facets of Takeshi’s (Momo) personality. The master/pet concept was cute and not overly sexualized. It did ring true with how pets give us so much patience and love, even though Momo was a human guy. I liked how the story showed us how broken the main characters were due to other people crushing their dreams and hopes. This realization by Sumire and Takeshi, brought about some beautiful scenes. There was no awkwardness due to the 10 year age gap, (although in 2023 American Hollywood people are marrying over 20 yrs age gap, so it’s not really shocking), because of there not being any sex between master and pet. Also Momo/Takeshi was 20 yrs old (already an adult), who had plenty of sexual experience due to previous relationships. The other sexual moments in the drama were tasteful done without over doing nudity. In some ways Takeshi was more mature than Sumire. There were many moving scenes between those two, as their relationship grew and their characters changed due to each other. Comedic moments were well crafted, didn’t feel forced or predominant. The ending was satisfying.
Subtitles:
Very well done, I wasn’t annoyed with bad grammar.
Acting:
All of the cast was well selected and brought their characters to life. Shison Jun was amazing showing the diversity of roles his character played and the emotions he had. There’s one part were he shows his anger and it meshes so well with the story. He was superb in this role and seeing his dancing was a treat. Iriyama Noriko really pulled off the naivety and introverted character of Sumire. The two of them had perfect chemistry for each stage of their relationship. Decent kissing that didn’t gross me out, for the most part.
Music:
The theme song Rainbow Rain suited the rom-com well and the other music was okay too.

DISLIKES:
Production:
Shaking camera syndrome in some scenes, but for the most part it was okay filming. Also the last few episodes felt a little rushed.
Editing:
There were some episodes that seemed choppy and didn’t flow as the scenes changed, which I think is sloppy editing.
Writing:
There were a few times that sexual intimacy was forced, especially between Sumire's Sensei and herself. There seemed to be only one time (his angry moment) between Takeshi and Sumire, but it wasn’t as cringy. The female pet didn’t fit as well and was given less time to develop, hence having no impact.
FX:
The facial wounds on Takeshi healed too quick, like they forgot to put that makeup on.

OVERALL:
I watched each episode and practically binged it. It’s an easy watch, without too much angst, but a little heavy on the characters crying. I enjoyed it and rewatched it, to leave a review, because the first time I didn’t. I would recommend it for anyone to watch.
