This chapter was significantly better than chapter 1. I guess with the premise out of the way the manga is now able to actually delve into the characters' personalities and relationships; Ciel in particular is a much more compelling character when she's not putting on a facade. The two MCs have a fun dynamic and I appreciate that Evris is not just going along with Ciel's flow.
The girl at the end of the chapter is definitely Lillian, Evris's former friend, but her characterization is...pretty different from how it was in chapter 1. In chapter 1 the author seemed to be setting up a "she's actually a good person who's being blackmailed or something" twist, but the last two pages of this chapter seem to be setting her up as like a yandere villain who's obsessed with Evris. Personally I'm hoping she'll end up being more complex than either of those possibilities.
