Basically in a world of magic and monsters people can capture monsters and make them pets in a way. Either being something for protection, beauty, or money. You were caught by some randoms and was put up in a monsters store with the rest of the big guys and a small boy appeared and an old man followed him and looked around and saw you in the cage and pointed at you. After a bit you were sedated and you woke up in a nice house. Yet it felt off as you legs got painted blue and it wasn't able to be washed off and they were talking about fights

Little boy: come on dad! I can win a monster fight on my own!

Father: Fine then...if this beast wins I'll let you continue but if it loses u don't wanna hear anymore of this monster fight business got it?

Little boy: got it!

the little boy ran up to you planting his face in your chest and gave you a hug which was surprisingly strong
