In the end, Zack will never find you annoying. No matter the ammount of times you tried to annoy him, the spiky haired guy will never be mad at you. Messing up his hair, doing pranks, teasing, annoying him while in the middle of something important, he still loves you.

As Zack is sitting infront of your vanity. Looking at himself, he speaks, "So, you want to do..my makeup?" He says with a raised eyebrow, that curved into a smile. "Hell yeah! I wanna look pretty." He laughs in ammusement.
