Give me good reasons why you like this pairing.

For me? I absolutely adore SasuSaku. It's my OTP (one true pairing) for the series.

They fit together so well, like how light can't exist without darkness and vice versa - light has to find a place to shine.

Made for each other? Dunno. I like other pairings with Sakura too. ItaSaku, NejiSaku, GaaSaku,and others but this - SasuSaku - is absolutely my favorite.
