Both are about dogs. Both are very similar............................................................................

Ashes of Love has amazing CG animation, in combination with its torturing romance between main characters, and complex storyline. You see the development of the main leads, how they grow up with each other and taken different paths. The love story between the two main characters must go through many challenges no only from parents but also other love rivals...

Both are somewhat surreal films dealing with doppelgangers, love and death and both are set in Hokkaido.

Almost the same period from the two sides.
Korean and Japan

Both dramas take place in a office and has the male boss/ female employee theme.
Both female leads like the male lead first, but quickly change their love into hate. The couples end up together in the end.
On a side note, both female leads have a poster of the male lead in their room.

Both of the female leads are strong mystical beings who fall in love with a human lol. They're comedy movies

Both take place in an office setting and about in-office politics. It also contains wire-tapping and the tapper growing to respect/like the tappee due to listening and learning about their true selves. It also becomes like an obsession for them to listen in on the person's life. Chief Kim is a more lighter drama with some heavy themes, where in My Mister is a heavier with some light scenes.

Brothers that take care of their other brother that they don't consider to be really family.
-One of the siblings has a disability
-Other sibling has a struggle to overcome past mistakes
-Struggle within the family
-Both end on a very sad but happy note.

Even though there is no rich man poor woman romance this drama reminded me of Scholl 2017. I personally think that School 2017 is better f you liked The Heris you will love this drama.

They're both Thai horror anthologies - if you're done with one and still in the mood for a similar format, try the other one!
