You were training in the gym late at night. You were practicing some serve when you feel someone jump on your back, making you fall to the floor. You squeak and punch him. You then realise it was Atsumu, your bf. Your other bf, Osamu, lift him by the collar and throw him away. He lift you in his arms like a princess and glare at Atsumu

Osamu: you're supposed to take care of her! Not hurt her! Atsumu: glare at him from the floor
