Yeah the premise is a bit overdone. Nothing's wrong with that personally speaking. Just because a bakery has perfected a certain cake does not mean other places can't make that same cake. However, my main problem it is the execution is itself very much by the books. Whether the story structure, the character dynamics, the plot beats... everything is predictable that at some point you just breezes through. On top of all that, the story does drag the angst a little bit. As a result, the drama fails to become delicious because it's lacks any new iterations. Characters is also pretty stereotypical. Of course it's a GoldenRetriever x Black Cat pairing. Of course the Golden Retriever is the one losing his memory. Of course they fought because of the Black Cat's internalized homophobia. Of course the Black Cat is the one hiding and keeping his pain by himself.

That being said, the execution still feels pretty solid. Nothing feels rushed, and the payoff at the end is still present and still very, very sweet.

All in all, it's still a good delightful cake.
