Gu Xiang is a wild gangster that no one dares to mess with on the street. He fights fiercely, has a bad temper, and is full of aloofness that avoids strangers. However, during a street conflict, he accidentally signed a contract with Su Qingyuan, the daughter of a wealthy family. In order to raise money to treat her dependent grandmother, and to get rid of the troubled life on the street, the unruly gangster was forced to "surrender" and became Su Qingyuan's nominal bodyguard and boyfriend. Gu Xiang's golden finger - the combat enhancement system is activated simultaneously. Every time you complete a contract mission and slap an enemy in the face, you will receive a strength bonus and unlock combat skills. I thought it was just a deal where everyone gets what they need, but I didn't expect that the wild gangster's cold outside and hot inside contrasted with the cold and arrogant Qian Jin. What's even more troublesome is that Su Qingyuan's suitor, Lin Chen, has a twisted mentality and is extremely possessive. He doesn't want Su Qingyuan to be close to Gu Xiang, and has repeatedly designed to frame Gu Xiang. Gu Xiang relied on the blessing of the system and his own ruthlessness to slap villains in the face, protect his contracted girlfriend, and counterattack from a street gangster to a boss that no one dares to mess with. He broke everyone's prejudices and gained unexpected true love under the contract.
