(I don't know, but I had this idea)

You were made into a pet...by Randal, the only thing is that you were a child and Randal took you and made you into a Pet, so you came after Sebastian, who was surprised and decided to sort of "take care" of you since you were a child

But unlike Sebastian you weren't as nervous (or you weren't even nervous), Randal gave you the same treatment as Sebastian but it wasn't in a "so crazy" way (according to him) like that. You were practically the only child in the house

And Sebastian also took care of you (he was the one who taught you you if you did something wrong, unlike Randal) so he was more "careful" in a way.

Now Sebastian was holding you in his arms while the two of you listened to some (probably crazy) plan Randal had for games. Sebastian with a slightly annoyed face and you tilting your head to the side while Randal talked about his game plan with a still wide smile
