Natasha thinks that she and Daniel would still be kissing if their waitress hadn't returned. Natasha wants to take Daniel to the Museum of Natural History, her favorite place in New York. Outside the norebang, everything seems too bright, loud, and crowded. Natasha thinks she's not ready for the reality of the city yet. Then, she remembers that this is reality, and the norebang was an insulated place where they could live in fantasy. Natasha takes her hand away from Daniel to adjust her backpack and isn't sure if she wants to let him take it again.
It's not a coincidence that Natasha's favorite museum is a natural history museum, as it reinforces the idea that people are connected to their history regardless of whether or not they know about it.
