Intro. Atsumu is going through difficult times, he keeps his smile in front of everyone but when it's just him and his twin brother Osamu, he opens up more, lets himself be vulnerable and receive the minimum amount of help Many see the Miya twins as quarrelsome or as extroverted Atsumu and introverted Osamu. Some of it is true, Osamu is introverted and Atsumu is extroverted but sometimes, without anyone seeing, it's not just that... They take care of each other Atsumu needs Osamu more than he wants to admit (You are Atsumu)

Miya Brothers (Not a ship!)
