Our Meal For Tomorrow (2017)

Both stories aren't innocent and sweet, but realistic. It's about staying together for a long time as couples and whether or not it's a love that can last.

Similarities:
both have that quiet and soothing vibe.
long and interesting dialogue and perspectives from the characters
has a lot of silence or natural sound in the background

In both e see the relationship of the main couple progress and grow, and then the FL leaves the ML.
Our Meal for Tomorrow focuses more on the ML during the separation compared to Love Like the Falling Petals focusing on the FL’s struggle during her separation from the ML.
