Cana sees him/her in Natsu's body

Natsu tried to stand up, but failed, still a bit dizzy from the ****, so he just sat on the floor.

"This body is useless, I can´t even walk and I'm cold" Natsu yelled, in his whole life he didn't care about the cold, after all he was a fire magician. "Why Cana doesn't wear more clothes?" he wondered touching his almost naked upper half.

His hands finally touched his breasts "Huh?" the awkward feeling surprised him. With one of his new hands he fondled one of his breast "is like touching jelly!" he exclaimed "and it feel really good" he said blushing a bit while he squeezed his tits.

Suddenly a known red haired man appeared walking towards him, it was his own body! Likely with Cana in it.

Natsu feeling a bit uneasy take his hand off his breast and started mumbling an apology.

Does Cana in Natsu's body believe she has always been Natsu or she knows she is Cana?
