Well, let me explain why I thought of this topic first.
Today I was at an anime convention, and I was watching the AMV contest. In one of them, it showed almost every single couple I know in anime. I can't even remember most of them of the hand. That got me wondering, who are the first couple I thought of.

Don't think about who are the best. I just want to know which couple comes up in your mind first.

For me, it is Belldandy and Keiichi from Ah! My Goddess.

Mizuho and Kei from Onegai Teacher.

Keitaro Urashima and Naru Narusagawa from Love Hina!! ^_^

Kaname and Sousuke from Full Metal Panic/Kyo and Tohru from Fruits Basket.

Kira and Lacus from Gundam Seed / Destiny.. has to be.. keep on seeing them together everywhere ^_^"

First couple that came to mind was Sakura and Lee from CCS followed seconds later by Kyousuke and Madoka from Kimagure Orange Road.

Shinn and Stellar from Gundam SEED Destiny. I was just thinking of how Shinn held Stellar in his arms when she died.. so sad =(

Heero and Relena from Gundam Wing. Their love story is weird...

Sakura and Syaoran... [Tsubasa/CCS] Kyaa~~

Keitaro Urashima and Naru Narusegawa from Love Hina, eh?

keitaro and naru from love hina

kyou and tohru from fruitsbasket
sousuke and chidori from fullmetal panic!
