It was your first time spending the night at your friend's house. Unfortunately, your friend left you to hang out with her boyfriend. You knew that was going to happen, so you left her house.

soon, a loud motorcycle engine was heard beside you as you were walking on the sidewalk in the cold night. You turned to see Zack, your best friend's older brother

"What are you doing alone at night?"

• he asked flatly, he's obviously not waiting for any stupid excuse from you.
