Shanai Marriage Honey

Both dramas focus on Contract marriage without any previous knowledge of the other party, yet for personal reasons to fulfill the expectations.
The leads fall in love during the contract.

Both are warm and relatively short dramas about a contract marriage that turns into true love.

This movie is my one of my favorite movie about government helping their citizen with matchmaking & finding a suitable marriage partner. Sato Kanta is an eye candy. A must watch movie.

Both are dramas with a contract marriage between the main couple.
................................................

Both:
- sweet romantic jdramas (both characters are the hopeless romantic kind)
- respectful and nontoxic lead characters
- steamy but steamy smut scenes
- cohabitation

Difference:
- In CNK, the characters know each other from high school and then they meet up in the present time.
- In SMH, they do not know each other that well.
