All of the stories in this list are good for a cry or to make you feel sad but here are a few I highly recommend
Watashitachi no Shiawase na Jikan
10 years where I loved you the most
I Want To Eat Your Pancreas (The movie for this is also really good)
I wanna bawl my eyes out, I want manga or manhwa that makes me ugly cry, I WANT PAIN!
