Unfamiliar /kagehina AU/

Nobody knows where he came from or where he was born..but kageyama was not from Earth.Although he was human.He was a very confused guy.He was not a creature or something mythical,just a plain ordinary human...Or that's what they thought...It was a silent night when Kageyamas new life had began.unhurriedly,He pried his eyes open.He awoke from his slumber.His sleepy eyes gazed at the sight of the view.He was bewildered.Where was he? For the whole day.Kageyama wonders around Muddled by objects and other things such as TVs,Brushes,Phones,Tables,sofas etc That people use.For a whole week kageyama starts to learn a bit more about the world.He understands how humans live.Soon he learns about therapists.Therapists are supposed to be people who listen to your problems and try to help you deal with them.Maybe kageyama could meet a therapist and they could try to help him out.Tell him why he's on this Earth.
