I have no proof, but I think Lucy is not a reincarnated person.
While laughing at hearing my words, she replies nothing but some words like "Aba~" and "Abu~",
It's possible that she is hiding it, but not many adults can mimic a baby.
Even if that's the case, someone who desperately mimics a baby is not cute.
But, Lucy is cute.
To the extent I’m not bored being close to the crib.
I don't care anymore about reincarnated or not.
