No wonder why the “heroin” is so desperate, she’s probably trying to avoid a yandere route, although that doesn’t take away from her being hella entitled.
She new that our mc probably has memories of a past life yet she still chose the entitled “I own this world” route, so my sympathy for her if she is dealing with a yandere/ world ending bad end event is 0
Why can’t people work together if she is actually dealing with hard choices, and there is potentially someone from your original world, wouldn’t you take that chance and become friends?
