It's the same producer (Na Young-Seok). Basically, the same premise of having celebrities work but the difference is one is about a cafe and one is with a boarding house. Both are very relaxing to watch!

They give off the same atmosphere
Wintery themes, slow burning romance
Of course A Piece of Your Mind is more calm and toned down.

all genres are the same. The ML is a badass and the FL is also a lawyer in both. The ML is involved with mafia/gangs in both soo yeah seems pretty similar!

It has similar concepts to afterlife and evil spirits
and if you want to see rom-com this is the best
