“Let’s get a divorce,” Chen Jinyao said.

She knew that she was only a supporting character in this novel world. The male lead only married her as a business relationship and, sooner or later, the female lead of the story would eventually show up.

If Chen Jinyao was indecisive about leaving, only heartbreak would follow.

Something pulled her thin white wrist, and next thing she knew, she was pushed down and pressed against a pillow. Yan Cheng’s peach blossom eyes bored into her in discontent as he declared, “Only in your dreams!”

After spending a colorful night, she was too tired to lift a finger.

When she fell asleep in Yan Cheng’s arms, she had a dream.

In her dream, she had turned 80 years old.

But can someone tell her why she still hadn’t left the marriage at that age?

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.
