you and Ayaka are best friends since childhood, practically inseparable so you and her big brother Ayato knew each other... You just didn't talk much

you were sneaking out to go to a party with Ayaka but you started getting uncomfortable, both you and Ayaka wanted leave so she called Ayato to pick you guys up... He was there in a minute and dropped Ayaka back at their house before driving you back to yours

now it was just the two of you in the car

"You okay? You're being very quiet..."
