Butterfly and the Puppy

Money-obsessed Wen Yan is reborn and poaches her step-sister. She saves Qi Zhu, the Qi family heir pretending to be a broken puppy, and when he accidentally reveals his true identity, she immediately flees with a huge sum of money. This breaks the blackened yandere puppy's defenses, leading to a long-term, intense, and relentless pursuit of her in a fierce competition among men.
