In the last life, in order to force Su Yuan to give up his university place, his eccentric parents brutally broke Su Nan's legs. When Su Yuan was dying, only his sister-in-law, who was also in a miserable situation, secretly delivered medicine to him. Perhaps it was God's mercy that when he opened his eyes, he was reborn and returned to 1984 - the year when he was admitted to college. In this life, he gave up his university place and exchanged names with his brother Su Nan. From then on, Su Yuan changed his name to Sunan. He wanted to live for himself, avenge his enemies, save his ill-fated sister-in-law Wu Yue, bring everyone who had hurt him to justice, and protect everyone who loved him in every possible way.
