  Summary

  As non-human species on the Express, Dan Heng and Sunday have quirks and habits that may not be common to see. They are used to hide these aspects of them from others for fear of being seen as different, yet they slowly learn that the other members of the Express will always accept them and wish for them to be comfortable.

  OR: Dan Heng and Sunday bond over being different species and slowly grow more comfortable with showing their most non-human traits.
