Here’s a passage from the next chapter out of context:
It was strange, perhaps, to have never seen herself in a mirror before. Stranger still, to only be familiar with her current body as it felt in her blue nightgown — or, perhaps, as it appeared in a maid dress. Rem hadn’t considered it before, but now she couldn’t stop thinking about what she looked like underneath…
With her ____ twin sister right there for comparison, identical in nearly every way, it was somewhat easier for Rem to start conceptualizing herself as a physical being with traits that could be named. Both of them were — slender, and perhaps they looked a little bit more youthful than they were. They had somewhat delicate builds, but they were also sturdy and fit. Did the two of them perhaps exercise regularly, or was it more a mark of their heritage? Either way…
But there were differences there, too. The hair was obvious, but their eyes, too, were different. Rem had never really thought about it before, but even putting aside the color… Rem’s eyes were a little bit gentler than Ram’s, somehow. She was a far more vicious person, but her eyes didn’t seem to reflect that reality very well at all.
—And also. Was it just her, or were Rem’s breasts…?
Ram blinked. “Rem?” she asked.
Rem froze as she realized that her twin sister had turned to catch her in the act of squeezing at her own chest, trying to get a feel for their approximate size beneath her nightgown. “Uh,” she said.
