Nora shows her own development differently because of how she grew up, she lost everything before she met Ren, and since that point he and her friends mean everything to her.

She appears unaffected by loss because she likely expects the average person she meets not to befriend her or to leave her already, so unless Ren leaves her she is unlikely to change.
