Bruh this chapter was on the next level. The way Seira was written is so realistic, its almost like the author has first hand knowledge of someone who acts like it. Cause I personally know a guy thats exactly like this.
Honestly, so far for me, the Seira chapters has been the best chapters to read.
In term of character growth (or well, more like character regression) seeing her trying so hard to grip onto her sanity, trying to make thing make sense, basically gaslighting herself into functioning. Its scary, dangerous and thats why its just that good as you wait for her to fucking snap for real.
None of the other characters so far has this kind of story tension yet (maybe Koumi, but not this far yet)
