Sorry Ex, All You Can Do is Regret!

In a world where a man can die and wake up back at the start of his own life, a second attempt at the same year is possible. Li Xiuyuan had given up an internship for his girlfriend Lin Jingya, and she humiliated him for it. He died, and then he was back. The second time, he takes a reserve slot at the civil service interview and is admitted with the highest score on record, which is awkward for Lin Jingya, who had attached herself to the secretary's son to get ahead. Once he starts work his section chief obstructs him, and he handles it without losing his temper. A friend from his university days puts him in reach of the newly appointed senior executive, and he is promoted to chief secretary. People at the office become careful around him. Lin Jingya hears about all of it.
