BLUE's manga / #messed up(2)

Technically I’m still reading this, but unfortunately I’ll never be able to finish because from what I’m aware, sadly the author passed away Quick overview! Girls whole family died (sister was r@ped and murdered, her father “killed” her mom, and then killed himself) which later she finds herself about to kill herself as well, when she witnesses a murder by a young boy, ofc the boy try’s to kill her, but instead makes a deal to kill the people responsable for her families murders and THEN kill her, so she’s like “Ight bet, works for me” FAST FORWARD!!(spoilers!) Last chapter the boy is found like totally fucking dismembered?! Like WHAT THE FUCK??! What’s goin on?? I really wish it was possible for this manga to continue! Because I wanted to know what happened next ya know???
