What is your favorite manga kissing scene, and why?

My favorite scene is..

..in Ai-Kora between Tenmaku and Hachibei Maeda. He has a prophetic dream that foretells a kiss between him and her after he begins feeling "love" for the first time. When everything in the dream comes true beforehand, he leaps to the chance and kisses her unexpectedly as he's caught in the moment. It's very cute, especially their expressions afterwards.

Runner up is Orange Marmalade in a recent chapter. It was also unexpected, and apparently voted for by the fans or some such.

In a world where troubled young hearts are besieged by evil spirits, only one can wield love as a weapon: the God of Conquests, Keima Katsuragi.
