少女は時計仕掛けの首輪を填める スチームパンク・クロニクル (竹書房文庫)

The setting feels so vivid and unique—I'm curious what sparked the idea to combine these elements and how much research went into it.

The chemistry was palpable, but I felt like their relationship developed quickly. Was that a stylistic choice or to keep the story moving?

Blending technology with period details created such a distinctive atmosphere. I wonder if the sci-fi aspects grew organically or were planned early on.
