Being able to get along with everyone in the Jackson Family without holding grudges is naturally the best scenario.
Mia Ginger thought the same way.
Most of the things she forgot were likely to be depressing and heavy on her heart.
Especially—
Being with Koa Jackson, she constantly thought about how Zoey Leaf was killed by Lydia Williams, unable to move on.
Because of this, she was even reluctant to go to the Jackson Family.
Now, having forgotten it all, even occasionally trying hard to recall and still failing, she slowly stopped forcing herself to remember those things.
Koa Jackson didn't take the initiative to tell her, and people around her weren't willing to inform her either. There probably weren't many pleasant events, so forgetting them might as well be fine. It wouldn't affect anything anyway, and she would remember when the time came eventually.
They were already a family; what kind of significant grudge could there be?
