I'm a hoarder's daughter, but after I picked up a banished prince (a super-talented wizard turned into a child), he doted on me!

https://www.cmoa.jp/title/321061/ At a ball in the castle, Prince Lucifer, harboring resentment, loses control of his magic and curses Countess Beatrix, who happens to be there, with the curse of "finding anything she can find." Since then, the young lady has spent her days collecting garbage in town and has become known as the "Garbage House Lady." However, she herself prefers her carefree, slow life to the restrictive life of aristocrats. One day, Beatrix finds a boy who has collapsed in the town and takes him in to live in her mansion. But that boy is actually the prince himself. He had been transformed into a child by royal decree and banished from the castle. A peaceful and mysterious cohabitation begins to change the relationship between the two!?
