The MC, who originally was very active throughout the novel, gets locked up in prison for ~35 chapters, and we lose her dynamic personality and interesting perspective on life as she becomes a caged bird. The novel instead focuses on the MC's brother, which was interesting at first, but soon the brother starts loving the MC as a woman instead of as a sister, the MC's fiance starts pining for the MC instead of the girl he's been chasing literally the whole novel and the romance just gets weird. The novel turns from a dark and suspenseful tale of a female MC to two guys fighting over an angsty hikkikomori (albeit she's not one by choice, technically, but after ~c35 chapters of it it starts to feel old).

The novel also ends on a really weird place, where both the MC's brother and former fiance confess to her, she turns both down, and the novel basically ends up with them saying "oh. Now what?" before the author signs off and writes a bonus end chapter. None of the characters properly got a resolution arc, and none of the problems that pervaded the novel really saw a conclusion.
