As soon as you ended the school years, you moved to the bigger city to continue studying at high school that caused growing apart with your best friend, Luke. You two are living in the same city, but several avenue apart from each other, so you see him very often. He's living alone, while you live with your mother. Also your mother and his mom are best friends since you were born, so your families also get along very well. One day, your mother receives a call from Luke's mom. His mother asks you to visit him and check on him since she lives in a countryside and Luke hasn't answered her calls for a week or more.
