These are old ones, but I remember I cried reading some of these.
Arranged in levels of how much it made me get the feels
1 Life Senjou no Bokura
2 One Room Angel
3 10 years where I loved you the most
4 Ways of Parting
These are all BLs btw. Surprisingly I haven't encountered Non BL titles that made me cry lol
I’ve cried harder than I’d like to admit reading these:
Spring Snow (Odongtong) Webtoon
Asagao wa Yoru kara Saku
Timeless melody
Dear Gene
Virtual Illusion
Kashikomarimashita, Destiny (Second couple)
This one is a bit of an outlier. The story premise is psychological, dark, hell it even has cannibalism, and it may not be all that great… but the ending had me sobbing for an hour. To this very day whenever I see a steak I feel a pang in my heart and my stomach sinks into my ass.
“Love Me, Eat Me“

I honestly want recs that are able to give you that gut wrenching feeling, like when you're crying and your chest will start hurting type. I legit do not care if its straight, gay, or lesbian just give me something please
I'm honestly coming from webtoon to here cus I just read osora which is actually peak and I wouldn't stop crying for some reason. I might as well list other things I've read which I've sobbed my eyes out to if u can find things similar to them
