Neptunus and Nuansa are now in a large traditional market. Nuansa haven't talked much since the two of them left the restaurant earlier, while Neptunus doesn't feel any specific feeling because he thinks Nuansa didn't hear him when he was talking to himself earlier, and Nuansa did make sure Neptunus didn't notice that she was listening to him when he talked to himself earlier.
Neptunus should have been confused because Nuansa had not talked much since they were on the way to this large traditional market earlier, but it seems that the man does not think about it because he thought Nuansa just feeling nauseous because of her belly that is full now, and he actually feels a little nauseous now with his belly not returning to its normal shape, a.k.a it still bulging due to fullness.
