The miya twins parents were killed while they were inside the house with them..

Atsumu and Osamu were adopted by the man who killed their parents although he paid more attention to them than their parents so they never blamed him for their death..

Osamu collapsed one day while him and Atsumu were playing tack and his breathing was unheavy he even stopped breathing for almost a whole hour

Atsumu started to scream and cry as their adopted father Akigeru held him close and reassured Osamu would be okay..

During this Sakusa's dad was having a meeting with Akigeru about something and Atsumu bumped into Sakusa while Osamu bumped into Suna (Sakusa's cousin)

But the young boys forgot what Sakusa and Suna looked like so they just forgot about them and with Osamu spending almost his whole childhood in the hospital he didn't remember anything about Suna while Atsumu only remembered Sakusa's first name
