If you're famiiar with "cat boys" and all the tropes that come with it, you'll already know how Meow will be portrayed: as a naive and innocent, sometimes childish, always playful, very young-looking boy with a slight build and a smooth and soft face.
If these stories about cat boys (whether in fan fiction or in manga/manhwa/manhua) do not devolve into straight-up porn, they usually stay light-hearted, soft and very, very cute. This one stays consequently on a PG level of intimacy, there's some toe holding, hand holding and one cheek kiss (where the kisser has no romantic intentions).

Content warning for some animal abuse, although we don't see any bodily harm.

First: The acting is okay. We are used to the newbies in Thai productions. and this is a bit above average. The main characters' actors, James and Gap, are more than above average, Gap did well in portraying his change from lonely artist to overwhelmed room-mate to a guy who is very much in love. James is a perfectly innocent cat-boy, showing every bit of his emotions very clearly, but without more exaggeration than the genre needs.
Second: The intro song is annoying, but bearable, the rest of the background music non-remarkable.
Third: I liked the sets, the locations and the editing. Not outstanding, but never empty and always realistic, fitting to the genre.
Fourth: I would have liked the ears to look a bit more realistic, and there were some instances when the actor's earlobes were visible.

Regarding the story, the series shows its manhua roots -- I did not find much about the original material; it seems that the manhua is at least 68 chapter (or books?) long; the few episodes of the anime version that I found were only a few minutes long. I suppose (and I just extrapolate from other manga and manhwa) that the oringinal material is one of those episodic endless manhua that never go anywhere, have little to no character development, and have no "ending", because if the couples would become official, the seres would be over. I guess that this is the main reason that this live action series's ending is more open. (Also, would anyone call someone their lover if their relationship is still unclear? Of course they don't.)
I would have loved to see more backstory for Meow, and I'm unsure if it's because of time constraints of the series or if the original did not provide more info? I do wonder why Meow is more childish than other members of the Ear People -- he's obviously slower to learn, but it also seems as if he's been sheltered from the wider world by his adoptive family? There's been some allusion to mistreatment as a little kitten but that doesn't explain everything.

Considering all the couples have the potential for power imbalance (adult / child-like cat boy, student / teacher, boss / intern) -- there's no need for concern here. The partners with more power never misuse this to push anything. The female couple is the most balanced -- while one is the bss, the other's compliments and clear adoration always melts the boss's heart. The second male couple also has its balance -- it's the student who would like to have more intimacy and tries to get closer. /Also, I think that Evan is more of an assistant than a full professor?)
Considering the main pairing: Even though Dermden (the adult artist) feels some kind of attraction in the first episode already, which evolves into love, and even though he would very much like to have a romantic relationship with Meow, he never acts on it. He even avoids situations where he could potentially cross boundaries, to Meow's great confusion. In the end, Dermdem is just happy that he has Meow in his life, and he'll take anything he'll get.

Overall, a nice and light watch, if you can accept all the tropes that come with cat boys and if you like some innocent romance.
