Manga with suicide themes or just depressing (if you're on this list, are you ok?)

Just a sad one shot, too short to make me cry tho

Same author, just sad

It's not a sad ending, BUT I CRIED

It's just a weird bullshit, don't read it, it isnt good

I liked it, quite disturbing tho

They were the reasons of her suicides, they know it

Living knowing when is everyone going to die
