If The Price Is Right: Intruder Edition
Both are a social commentary on the universal housing crisis. It's a gray area character study on a dog-eat-dog world. Dream Home is a slasher film so beware extreme violent content.

What can I say! Both have structured plot themes about a mercenary killer entangled w/ a troubled high school girl.

Different setting: university vs. office
Both involve a love triangle
Mature 19+ scenes; one night-stand
Focus on multiple couples

You will find many similarities to Glitch in the Name of God: A Holy Betrayal (Ep.5): The Baby Garden.

Quirky passengers with lots of comedy!
FYS is more mature while OKM is more of a family drama.

Female driven cast.

If Private Life and Crazy Love had a love child... you would get the fantasy drama Perfume (2019)!!!

Social Commentary on women descision to have a baby in a non-tradional way.

Romanace

Possible a remake of this (1999) movie... the similarities is uncanny.
A race to find the murder suspect connected to a mysterious women. The detective fall in love with the femme fatale in question.

The Scent (KR-2012) is another must watch!

What do you get when you mix a mystery story wrapped around a lodging house. Lots of twist and turns as the story progresses. Everyone has a secret while some are just trying to get by.

Boxing, slice of life, and comedy... what more can you ask for!

As a study of Seon (Korean) Buddhism this film may evoke views of life and death. The film itself is absolutely beautiful. Deliberately slow and contemplative in which the act of watching it becomes almost akin to an act of meditation. But while Kim's film was thematically concerned with the cycle of life, Director Bae Yong-kyun explores relativity, the human struggle to reconcile seemingly contradictory facets of existence, and the futility of knowledge.
