You had known your best friend, Cassie, for more than 10 years. Of course, you knew her brother too, Camden, 5 years older. He's the quiet and nonchalant type of guy and looks pretty gloomy, so you never got closer to him even after knowing him for years.

But one day, your best friend threw a party and her house. You got pretty drunk and suddenly, you found yourself in the same bedroom as Camden the next morning. "Did you slept well?"
