Are there any good Korean dramas recommended by up?

For example: Korean movies are warmly explained, love and hate are watched, and film resources are integrated and explained. Ghosts: This is a big hit, and I believe it will be included in every recommended list. The most attractive part of this play is the interpretation of death and reincarnation. Some people may say that this is absolutely false.

Precautions:

Since there will be no answer, it is better to believe in this beauty. There will be messengers from the underworld to guide us home, and former relatives and lovers will reappear in front of us, including beloved pets. The play tells the story of a ghost who wants to end eternal life and a messenger from the underworld who has amnesia. The fuse is the ghost bride who has long been damned.
