Currently at the top of my head since I’ve been too depressed I’m not sure which one I should recommend but I think you should read these 2 (one has a sad but happy ending, the ending for the second one it’s just... DEPRESSED)
Song recommendation while reading: songs by “Blegh” - especially <attachment love> on repeat, oh shit. Another can be listening to strong sad instrumental music.
Again these are older ones that I’ve read, upon more recent ones I don’t remember but I re-read these ones quite recently...
Manga 1: (SAD - ending it heartwarming and heartbreaking in my opinion)
—> the specific heat capacity of love
