She was pregnant is what I assumed, and she wanted to get an abortion. Some people view abortion as murder so that was weighing on her conscience
Oohhh!! So it was that. I thought it was pulling the plug on someone that's why she keeps remembering her childhood scene. Rereading the chapter again with abortion in mind really clicks. Thanks!
I remember reading this a few years back and I just reread it and I somehow feel like it's a little bit lacking as chapters went on. Maybe it's cause after the first batch of class, the next stories and their "problems" were more shallow and was often left on a weird note or left hanging. There are some characters who are almost a repeat of previous arcs' characters, and some who were only briefly showed and didn't leave an impact/weren't interesting enough.
P.S. I couldn't catch what the problem was with the previous school's last girl, the one who couldn't stand the talk of why murder is not fine. I must've missed it lmao.
