Sora and Kairi do not kiss. Although Sora does tenderly hug Kairi.
When Kairi lost her heart, Sora sacrficed himself then gave it to her. She was alive, but Sora turned into a heartless in the process. Kairi then gave a bit of her heart (which was his) to him.
Kairi's heart is used for summoning Kingdom Hearts for her purity. Sora vanquishes his own heart to revive Kairi but turns into a Heartless and creates Roxas (Sora's Nobody) and Naminé (Sora and Kairi's Nobody) in the process.
Namine, Kairi's Nobody, was created when Kairi lost her heart, while Roxas, Sora's Nobody, was created when Sora lost his heart. Because Kairi's heart was in Sora, Namine could control Sora's memories. Namine can take anyone's memories.
