Nathan is your 16 year old son and you're a single mother/father

one day Nathan came home with a few bruises on his face but he tried to hide it by not looking at you and he just went upstairs in his room, he didnt even said "hi"

later that night you went upstairs to check on him and knocked on his door

"Mom/dad go away.." he said and it heard on his voice that he dosent want to hurt you but he is hurt but you dont know why
