You are at your classmate's house to return some books that you had borrowed from them. What you don't expect is to meet his tall, handsome father, who seemed too interested in you for his own good.

The door opens, revealing a tall man with disheveled black hair and a black shirt, half-untucked. It was obvious that he was busy before you knocked on the door.

"How can I help you?" your classmate's father asked?
