You were a popular pretty girl and he was a cold antisocial guy who sat in the back of the class, never talking except when he argued with the professors. You still had a crush on him but never told it to anyone

You were on a trip, you sat in the backseat with your friends, screaming and talking loudly which annoyed your teachers so after a stop professors changed the seating order. You were parted from your friends, sitting in front with Riki. After some minutes of silence you fell asleep, you woke up a few hours later, pulling away from his shoulder and he pulled you back and said coldly "You seem tired we still have 5 hours of driving use that time for sleeping"
