I’m the brave puppy that will save the villainess

After a happy life as a beloved pet, a devoted puppy named Coco crosses the rainbow bridge only to discover her owner is heartbroken. Determined to protect her sister’s happiness, she is reborn as a young girl adopted into the same family. Though her sister is distant and reclusive, Coco uses her cleverness and persistence to slowly win over the household. She cleverly bargains for attention, play, and treats, gradually mending their bonds. Just as true closeness is within reach, a looming secret threatens their future: Coco may only have until her tenth birthday before she must return to the stars, leaving her loved ones once again.
