When Caelus first boarded the Astral Express, he didn’t have a room to sleep in, so he settled for sleeping on the sofa in the parlour car.

This was fine until he complained that parts of his body would ache the next morning due to the couch's lack of support, hindering his performance.

Consequently, Himeko suggested he stay with Dan Heng until his room was ready, knowing the archivist would likely be the least bothered by it.

Unfortunately, they didn’t count on his futon being so small, and now they were squished together atop a thin mattress on the floor of the archives.

“This is… rather uncomfortable.” Dan Heng remarked, shifting under the duvet in an attempt to distance his body from the Trailblazer's.
