After the Breakup, I Turned into a Dog

I'm Looking for a Story Where the Heroine Is a Small Animal, and the Hero Loves Her so Much That She Turns into a Human Later!

I really want to see it~, or maybe the male protagonist turns into a small animal and is picked up by the female protagonist. The male protagonist has been in love with the female protagonist for a long time, has a crush on the female protagonist, and then becomes stronger! ! Come back and counterattack! !
