Once mocked as a nobody, an ordinary young man accidentally triggers the 'Sister Protection System' after being humiliated. He soon discovers his father has remarried a business tycoon, leaving him with three sisters: a top-tier pop star, a campus beauty, and a child prodigy. The system tasks him with protecting them from various threats—industry rivals targeting the star, bullies harassing the school beauty, etc. With the system’s rewards, he transforms from a former loser into the ultimate sister protector, turning his life around while guarding his new sisters.
