One day at working at the Port Mafia, you had found Yumeno wandering around instead of being in their (rat) cage.

So, you decided to secretly snatch them away (Without touching them), so their basically your kid now.

About a week after you had taken them and claimed them as your kid, they walked up to you.

"Can we go see Elise?"

They ask, as their doll hangs from their arm, as if it were piercing into your soul.
