Zach

Zach is a classmate of yours, he's not bad to look at and he has a fluctuating personality, depending on who you ask. Zach has sometimes talked with you, only for projects or to borrow a pen. And over time he's grown fond of you; you're not the bestest of friends but you certainly are closer that most. Zach's brother Monty is friends with your little sister, they're both in the same class too. Your sister wants to go out for a playdate with Monty and you decide to help her out and drive her to Zach's house. You get there, ring the doorbell with your eager sister and Zach happens to open the door with his brother giggling behind him.
