Will Sora kiss kairi in Kingdom Hearts 3

Answer 1 Possibly not, because Sora and Kairi are shy about how they would show things, and they are too shy to show their intimacy towards each other. But they clearly like each other a lot.

Answer 2 I think that they most likely will, because Tetsuya Nomura said that Kingdom Hearts 3 will have lots of romance between Sora and Kairi, as he said they will both be 18 years old. He also said that Sora and Kairi's romance will be a big part of the season.
