For
whedonland Ya! I Ship It Manifesto Challenge
So why do I ship Willow/Oz well #1 Because you can literally see the moment when she realises that this is a great guy who she could really like.
WILLOW: "Do you wanna make out with me?"
OZ: "What?!"
WILLOW: "Forget it. I'm sorry. Well, do you?"
OZ: "Sometimes, when I'm sitting in class--you know, I'm not thinking about class, 'cause that would never happen--I think about kissing you. And, it's like everything stops. It's like, it's like...freeze frame. Willow kissage. (pauses) Oh, I'm not gonna kiss you."
WILLOW: "What? But...freeze frame!"
OZ: "Well, to the casual observer, it would appear that you're trying to make your friend Xander jealous, or even the score...or something. And that's on the empty side. See, in my fantasy, when I'm kissing you, you're kissing me. It's ok, I can wait
#2. Because they break my heart over and over again (They are a Joss couple afterall)
Willow: "Oz, don't you love me?"
Oz: "My whole life, I've never loved anything else."
Oz: It was stupid to think that you'd just be... waiting.
Willow: I was waiting. I feel like some part of me will always be waiting for you. Like if I'm old and blue-haired and I turn the corner in Istanbul, and there you are. I won't be surprised... Because you're with me, you know?
Oz: I know. But now is not that time I guess.
Willow: No. What are you gonna do?
Oz: I think I better take off.
Willow: When?
Oz: Pretty much now.
And all the other reasons because of her close personal relationship with God, because their love is so van based, because he bought her a pez witch, because he's a werewolf in love, because of panicing and because of how ridiculously cute the two of them are together.
