Umm.. This is a prequel to Chou yo Hana, but a lottttttt darker. Mofo...
Seems he had an abusive dad, so mom remarried. His uncle is kind and caring. And they were pretty much in love until mom's dead..
Uncle snapped at some point and began being possessive over protag. Raped, got him a womb tattoo, etc. Still he's gentle??? Idk he just lost his mind
