After departing the border curtain and embarking on this prolonged "Journey to the End of the World," the crew members of Homeloss and the Brilliant Starship have gradually formed a new and tacit connection. Sometimes, people from the two ships visit each other; sometimes they share what they have; in most cases, Ai Yi is the bridge facilitating communication between the two vessels—and these connections, along with the "everyday" built upon them, seem to be quietly becoming an anchor for the "humanity" within every person onboard.
Because they are far away from the civilized world, far from crowds and society, the travelers particularly need human interaction—when the mist at the end of the world envelopes everything, being able to confirm each other's existence in the fog becomes particularly important.
