It's not rush hour, and a lot of people get off at Shinjuku. And since they make it to the platform not long after the last train left, they're first in line to get into the train car. Odds are, there will be at least a couple seats open.

The boys choose to stand, though. It's only a few stops to Ikebukuro, after all. They continue to talk and joke amongst themselves, like boys do.
