I know this recommendation is not a documentary about an ethnic group and lifestyle..
But it is healing and feel good slice of life that made me remember it while watching to the wonder.

Different setting, not noona romance ..however if you like the vibe of something in the rain and the midnight romance in hagwon you'll feel it in one spring night (same director
and producer or screenwriter I think)

Although it's a different setting (sport setting) and a different pace as expected from a sports drama , they both share the ex-student with teacher relationship..noona romance if you will

Remembrance of the past dwells on the past and how it affects their present.
My liberation notes dwells on the present and questions the possibility of a way out.
Both seek closure in their own way.

Healinggg!!
Despite that our blues focus on several main characters, will love in spring shares the same vibe:
The world didn't stop at said inconvenience.it will be okay !

Tho splash splash is kdrama set in historical drama, the time travel component is present..the short length sweet series aesthetic is the same in both..

-both are about the romance between a deaf person and someone they love
-silent tackled their issue in a more mature and healthy way
-aishiteiru to ittekure give a slightly similar vibe with more nostalgia and melancholia of 90s dramas
