All of the following yaoi manhwas have a long story and all of them are really worth to be read!
- Ways of parting ( https://www.mangago.me/read-manga/ways_of_parting/)
- The warehouse ( https://www.mangago.me/read-manga/warehouse/)
life ( https://www.mangago.me/read-manga/life_senjou_no_bokura/) I cried all my tears with this

Does anyone have recommendations of bl or yaoi where it’s heavy angst with no happy ending, I don’t want ones where it’s just abuse or grape but rather like a tragic love story
