Evelyn had known that both her parents loved her very much from the beginning, and their adoration for her had only grown since then. It was only natural since she was a good, adorable and obedient daughter.
She knew it was only a matter of time before their affections naturally reached the level required to obtain their enhancements. And aside from their natural interactions, all Evelyn did to raise their affection was learning archery and painting from Desmond and Isabella respectively.
It did increase their time together a little, and allowed them to interact with each other a lot more. But Evelyn believed that even without doing so their affections would have been maxed out eventually. It would just take a lot longer.
But two thousand points of experience was too great a boost for her to not want to have as soon as she could! After all, it was more than four times the experience she had managed to acquire in her entire life so far.
