Harry-
Laughs: The way he squeezes his eyes shut and giggles like a little kid make your heart swell. His laugh is music to your ears, and it's so contagious. You always find yourself laughing or smiling along with him, simply because he's the most adorable thing in the world. Every single time he laughs you fall about more in love with him.
Liam-
Pouts: You think it's cute, and he knows it. He often uses it to his advantage, shooting you a pout when he wants you to stay in bed for an extra couple minutes, to watch the movie he chose instead. No matter how hard you try, you can't stay away from that face.
Louis-
Opens up: Louis has a big heart, and you feel special that you're one of the few people in the world that get to see that side of him. You love to hear him talk about himself, his worries, his passions, his past. The fact that he can be so vulnerable and open with you lets you know that you mean more to him than you'll ever know.
Niall-
Acts silly: If you're in a bad mood, Niall will never fail to cheer you up. He'll crack a few stupid jokes, or do an odd dance, or even reenact a scene from your favorite movie, anything to see you smile again. He's a naturally positive person and his energy has made you a much happier person since he's been in your life.
Zayn-
Gets jealous: There's something about how dark his eyes get and the way his jaw clenches when he sees another guy touch you that makes him absolutely weak in the knees. What's his is his and he makes it known. He'll tighten his grip around your waist and sometimes move his hand to your butt and squeeze it for everyone to see, he'll whisper in your ear with a gruff voice "you're mine". He never fails to remind you later that night just who you belong to.
