My name is Coco. I’m a dog with fluffy white fur that looks really charming. "If there’s a next life, please, be born as my daughter. Okay?" I spent a happy dog’s life with my sister, then crossed the rainbow bridge. ‘…Why does everyone hate my sister?’ No! The brave puppy will protect my sister’s happy life! …And so, I crossed the rainbow bridge again and was reincarnated as her family’s five-year-old adopted daughter. But getting close to my sister is not easy at all. "Don’t call me sister. You’re not my sibling." It’s okay even if she doesn’t recognize me as Coco. This time, I’ll be the one to approach her first. "I just… I just wanted to get closer to you, Lady Chloe." So, sister, can’t we be close again?
