Info about Yourself/(Y/N)

This story is about (Y/N) and his friend Hinaru Yukiteru ( The son of Amano Yukiteru and Yuno Gasai ), Hinaru deeply cares about (Y/N) and will protect him from anything, but when he figures out (Y/N) is about to get murdered by his stepfather who is secretly a murder and is apart of a Mafia, Hinaru is going to take matters into his own hands. ( This is my first story so expect to be some dumb shit in here, and also this is a Sequel/Au for the anime Mirai Nikki aka Future Diary bc I'm a literal fan boy for that anime )

I'm also gonna remake this storyline and make it better once I'm done with this story ^w^
