But the moment he burned it down little did he know that touru's parents were inside at the time and that's what caused their death. So criminal for arson and murder.......da da dun dun!!!!
But if the main character's parents were killed in house then he's probably know that and not ask what it used to be...
if this goes down a twisted path, he was too young so no one told him the specific of things and all he knows is that his parents died cuz of unkown. and being a dumdum touru is he didn't ask any further. it's interesting that the grandpa has SP so how important of a figure is he? but this doesn't have a tragedy tag so i'm just letting my imagination run LOL
I love the fact you're theorising XD
I never take the time to actually sit down and go, hey perhaps this'll happen
His hatred for the house?
The siblings probably treated him like shit because of his past.
That empty lot in the back?
He probably burned it down because it had an awful memory or it was merely an accident and the family uses it against him
