Also these didn't make me cry but still recommending them cause they're still sad
"Leia"
"Just be Friends"
"Rolling Girl"
"Solitary Hide and Seek Envy"
"The Lost One's Weeping" (My go to song everytime school stresses me out)
"Sarishinohara"
"The h@nged girl in the haunted house"
"Secrets of Wysteria" (This was based off the serial killer Albert Fish's crimes)
"Alice of the Human Sacrifice" (this is horror but it's interesting so just recommemding. It's really catchy too)
Also, you should definitely check out the 7 Deadly Sins series of mothy, If you haven't yet. "Daughter of Evil" the prequel of "Servant of Evil" is part of it.
Any vocaloid song that made you cry because of the song and the story were both beautiful and sad ? Like "Servant of evil" to me
