Ma Hu, a 58-year-old veteran hunter, is knocked off a cliff by a wild boar and unexpectedly reborn back to the year he turned 21. In his past life, he was framed by his so-called friend Li Xiaoming, forced to marry Li Xiaoyue — a woman carrying another man's child — and raised someone else's son for seven years, only to end up with his family destroyed: his father died working in the forest farm to support the family, his sister was shot and killed in the snow, and his mother lost her mind. Living this life again, Ma Hu swears to change his fate and protect his family. The moment he wakes up, he is bound to the 'Pet Attribute Point System', which can strengthen his pets and feed their abilities back to him. He first devises a plan to let the idler Xu Dali see Li Xiaoyue in a compromising situation, forcing the Li family to marry their daughter to Xu Dali instead — freeing himself from being a stand-in husband.
