I found the atmosphere and writing to be quite similar to each other. They're both about people finding solace and happiness in each other and finding their footing in life.

Both revolve around 2 couples getting entangled due to an affair. Both the female leads are ruthless and will do anything to get their way.

They both have this really eerie and bleak atmosphere. There are also many similar themes such as hypnotism and characters.

Both of them involves the usage of suspicious tapes and a creepy female "ghost". Overall, I'd also say they have pretty similar atmospheres.

Both have an eerie and sinister atmosphere. Both stories are revealed to be much more than what they initially seem to be and have a layered narrative, shifting between the past and the present.

Evasive Inquiry Agency is also a story about people in search of gold. Really humorous and quirky. Hope y'all try this extremely underrated comedy!

Ok so they both have similar posters................. aaand both deal with marriage and infidelity quite elegantly so to speak.

They are both realistic portrayals of marriage and love. Both of them also touch several subjects including family and divorce with a quirky sense of humor.

April Snow is tonally very similar to Lost. Firstly, they share the same director. Both have characters that are emotionally pained and find solace in each other.
