The strongest Hero in history, Nakamoto Keisuke.

He was summoned to another world in the spring at the age of fifteen years old, and when he successfully defeated The Demon King, he was already thirty-two years old. He had finished his role in another world and returned to Japan, but the reality that had been waiting for him was, “Middle school graduate with seventeen years of blank period” label. He couldn’t find a decent job and had no choice but to spend his days working part-time.

Before such a Nakamoto, a beautiful girl who self-proclaimed had come to return the favor, appeared. “I’m the reward for Hero who had defeated Demon King”, said Angelica, a girl who came from another world that persistently tempted Nakamoto to make her his wife. Together with a high school girl who looks like Elsa, his beloved girl that he lost in another world, Nakamoto with his cheats skills got caught in a harem life.

After marriage, you cut off contact and have no more news of her. Re-establishing contact with Xu Qianqian will reward you with 300 RMB. Eighteen-year-old Jiang Nian glanced at the system task on the panel and then at Xu Qianqian living next door, falling into deep thought. Hmm... it seems the system came early. There is another issue: who is the future ex-wife? Hmm... Jiang Nian couldn't hold back. Being eighteen every year, he foresees a divorce in the future. The system issues a task to take revenge on the future ex-wife. Jiang Nian looked at the un-darkened version of the future ex-wife in front of him and fell into thought again.
