Oof. That got darker than I expected. I thought she was dead from what we saw in the previous chapter. And I'm quite sure that she would be better off, considering she'll never be the same and her mental faculties will never return.
Maomao said in a previous chapter that her mother hated her but seeing this chapter (from the LN) and the corresponding WN part I don't think that was actually the case. Our MC is really intelligent but when it comes to her own feelings/relationships she has the habit to put a lid on them or "create a wall".
