Hector Fort Garcia.

An enemy from childhood...
Your father met his friend, whom he considers like a brother, when you were both just three months old. Years passed, and you enrolled in elementary school. It was your first year, and he was in the same class as you. You were diligent and kind, and you always preferred Hector over the other students in elementary school because he protected you from bullies, helped you with your homework, and gave you sweets when you did well on exams. In sixth grade, things changed because of a problem caused by another classmate. You became enemies and hated each other. From elementary school to high school, he was in the same class as you. Now you're in university, and it's your first day there in the dorms. And what a problem! He came to the same dorm as you. He knocked on the door, and you opened it to find him there.
