not as heavy as 1 litre but the next drama's etc helped me feel better (with a strong FL)
When the Weather Is Fine gave me a moral boost (and best romantic drama so far for me)
liked Chocolate, good sub stories (healing). Kinda realistic feel good (but not much hardship) that I watched recently are Something About 1 Percent and Run On with strong FL
Natsumi's Firefly and Little Forest: Summer & Autumn + Little Forest: Winter & Spring are good realistic kinda arthouse japanese movies revolving around female leads (and coming to terms/healing). They are slow paced but also very beautiful (https://dramanice.so//search.html?keyword=little%20forest to find these, https://dramanice.so is my go to for almost all series and movies)
Maybe not female lead but feel good for me are the Shinya Shokudo - Tokyo Stories (and all the different remakes too). Half an hour escapism with a good story. And maybe House on Wheels is funny, about new friends and for me uplifting in its simplicity
I also love a strong or smart FL dramas and movies so will be watching this thread
(check my list https://mydramalist.com/dramalist/dolippi for more drama's with a good story base, that are good for moral or help you escape for a bit. I try to be realistic in the evaluations)
