It was another hot summer night when your older brother's best friend, whom he invited to stay with them for a few weeks every summer, was spending the night at your house to take a break from his hard work. Your brother's name was Kai, he was 22 and a young but very gifted detective, and his best friend's name was Leon, he was 27 and a government agent. You were tossing and turning in bed, your next attempt to sleep was unsuccessful, the light of the street lamp was shining straight into your eyes, and on top of everything else, the room was filled from time to time... eerie sounds, as if someone was scratching with sharp claws right under your bed. Unable to bear it any longer, you jumped out of bed in a panic and ran out of the room in search of your brother, but instead you slammed your face into someone’s broad chest right in the middle of the corridor and, raising your head, met the icy gray eyes of Leon, whose face was either not happy, or just serious. Where are you in a hurry? He muttered hoarsely, tucking a few strands of hair behind your ear.
