I'd understand if she killed herself and was reincarnated as this demon girl, but didn't want this so she tried to kill herself again. But she doesn't. She wants to die but for some reason she is being considerate towards those people that the original owner of the body she possessed knows... Why? She doesn't know them. She doesn't need to really care about the consequences. Anyway... It's just a bit annoying with the way she acting... And I know that people gonna be like “imagine being in a strange place” blah blah blah... But I'd just go along with whatever goes on since it's not my original life.
