This might be a bit longer than other headcanons from me ¯\_(ツ)_/¯

Bokuto, Kuroo and Akaashi know each other since they are born. Well, exactly from the day they were born.
Their parents were close friends from college and as they went older, all got excited when Mrs Bokuto announced she was pregnant. Nine months after that, Koutarou was born.
Then, nearly one year later, Mrs Kuroo got pregnant too and again, nine months later, Tetsurou was born. Little Koutarou, which is one and a half year older than Tetsu, went with his parents to the hospital to visit the baby and his friend for his life.
Then, a few months later, Mrs Akaashi got pregnant and again, nine months later, the two slightly older boys went to see their precious friend on the same day.
They all get along really good and a strong bond was build between them.
Now, some years later, they still are friends and their relationship is stronger than ever before.
Most of the people don't get their relationship, they usually just look at them with a strange look on their face because for Koutarou, Tetsurou and Keiji it's totally normal to cuddle and kiss each other on the cheek or on the forehead.
They grew up like this, they think it's normal. They just love each other so much it's normal for them to do things like this, even in public.

Things like this happen when it's nearly 4am and you drank a few Energy Drinks before.
I'm sorry (◐ω◑ )
Btw I'm sad that there is very little fanart of just the three of them together ;-;
