I adore Oz so much! And the funny thing is that the only icon I have with Oz in it, is the exact same one that you used!!

1. When Oz wins over Willow in "Innocence", he wins me over too:
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.

Oz: 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 okay. I can wait.

2. When Oz gives Willow another chance in "Amends":
Oz: This is what I do know: I miss you. Like, every
second. Almost like I lost an arm, or worse, a torso. So, I think I'd be
willing to... give it a shot.

And I love his reaction to the sex proposition, with the standing and sitting and then:

Oz: No, I have, but this is different. I mean, you look great.
You know, and, and you got the Barry working for you, and, and it's
all... good. But when it happens... I want it to be because we both need
it to for the same reason. You don't have to prove anything to me.

Willow: I just wanted you to know.

Oz: I know. I get the message.

3. I love Oz's sense of humour, so I love moments like this one in "The Zeppo":

Xander: But you need a thing, one thing nobody else has. What do I have?

Oz: An exciting new obsession. Which I feel makes you very special.

And this one in "Living Conditions":

Buffy: You're right. Ooh! She's even affecting my work, now. She's the Titanic. She's a crawling black cancer. (She brings her foot up, around and down onto a bench, breaking it in two.) She's... other really bad things.

Oz: On the plus side you've killed the bench, which was looking shifty.
