She wanted to survive her situation and live just for the sake of living, she literally has no aspirations or anything she wants to do after she survives. I feel like the story would be a lot better if instead of being like "I want to live" she could be like "I want to live so I can (insert something she's passionate about, even if just mildly)".

Tbh the FL is lame, she reminds me of a friend I had in high school who had zero to no personality, she was just going through the motions of life. The FL here is basically that too, her entire personality is summed by "I loved my brother who is now dead, he wanted me to live so I will do anything in order to live" and that's it, literally nothing else about her. Only reason I'm still reading is because they have a super cute baby later...
