Need to watch some tearjeker dramas as I received too much sweetness from Romcom dramas

Something like 1 Litre of Tears. Bonus if romance isn't the main plot. Thank you very much.

Mother but be warned, it is an tearjerker that breaks your heart. But then you can heal it with the next  sweet rom com ;).

Mother. Best kdrama I've ever seen. Bittersweet I would say

Not romance

Looking Up (movie)

Romance

Goblin

Us and Them (movie)
