Tofu Personified

Both series revolve around an animal/insect turning into a male human being to help a woman. A fluffy romance follows.

Man That Bakes Bread is about a cat that turns human, while Tofu Personified is about a dog that turns human.. and both of them have food names in the title, while the stories are not about those food xD

Both of thes dramas have pets that turn to human for the purpose of looking after or taking care of their owners.

In both shows the leads are socially awkward outcasts. They also idolize their popular love interest.

Similarly, there's a love story between an owner and a dog who turns into a human. The owner and the dog first have a close relationship as pet and owner, but when the dog becomes a human, their relationship evolves.
