I think it's got something to do with Belinda's sync rate with the character. At first she has no choice but to act and speak very rudely but when she accepted it and acted like Belinda, both inside and out, that's when the sync rate finally went up. And the rate going up might have also lessen the system's force which made her talk as she is right now and made her act how she wanted to although not fully. Or at least that's how I imagine it.
I came for complex characters since she was supposed to be bound by the system and be mean but this girl only talked rudely to the little kid for one chapter and after that the whole plot just feels so fluffy and somehow she’s able to be nice to everyone like???? It’s cute but not what I thought it was gonna be
