If I really want to feel wasted I just reach for Bronze. Every time I read it I feel sooo devastaded. You have everything in there - one'sided love, rape, almost death, injuries, jealousy...Sometimes of course occures a happy moment, but due to this you feel more sad, coz yosee how their happiness is washed away....
I guess mine would be Lovers Doll since the ending was sweet but depressing... Although plot-wise I find Not Equal to honestly be very sad as well considering all they went through to be together and get their happy ending ie. time travel to meet him and fall in love then leave so uke finally got over him and started a family only to find that his son was the man he met in the past. He couldn't even question his son because the time travel was when he was much older. No matter the nice ending, the process up to it was just very sad and kinda heartbreaking for the uke in my opinion as he had no clue who exactly his teenage lover had been and was kinda forced to accept it.
although it's not yaoi

this and all the deep love series killed my soul while i read them, the tragedy is almost unbearable ╥﹏╥
Lovers Doll is sweet and cute~ the extra make up for the chapter 5, the last chapter, so it turns to be cute and not depressing for me instead.( ̄∇ ̄")
As for not equal, I feel sad and pity for the uke but all in all it's still a happy ending to me it's a happy story, just a few sad parts but not depressing enough for me to actually want to cry so hard, since i have difficulty in crying, reading depressing manga makes me cry ╥﹏╥
Thank you though!!(⌒▽⌒)
I've read tons of heart wrenching manga and fanfics with no happy endings (usually love tri, or one died), too many of it that I cant even remember the titles. So I'm just wondering if any of you have your fav heart wrenching manga that really stays at the back of your mind?
