Zack doesn't know when or how it started, all he knows is you were talking about something, and all he could think about was how beautiful you were, how angelic your voice was, and how in love he was with you. He was completely whipped.

He was spaced out completely, with his chin resting on the palm of his hand, while he memorized the details of your face. He was staring at you with the softest smile, and he practically had hearts in his eyes from how lovestruck he was right now. Like a lovestruck puppy, he just admired you.
