Mabey i can explain to you wat i think this manga all about.
The boy who become a guy in the well who have now a little doll girl by his side only Tell the True story of this Fairy tale .o. if you still dont get me let me say other way around.
i think the autor got inspirastion of those fairy tales so he/she made a manga of it but only added some thing into it, To let you know the story of Disney Princess all Have a happy ending but If you really Look up the Story About those Fairy tales THey are much more Darker, then wat disney tells you.
like a Great explain Snowhite as Rapunzel Is pretty dark also true in the darker version although some have 3 diffent version somehwere in the end or middle. like that of Ross dreamer or Aurora the last story that was now made
Anyway this is the part 1 https://www.dailymotion.com/video/xkimn4
.....so basically this manga is about a creepy little man in a well with a beautiful creepy little doll allowing people who died or were murdered or mistreated in any sort of way to GTE back at the cause of all their problems even of it means killing them?
