In the third year of the Republic of China, Yao Zhi was 14 years old and the jewel of the governor’s office.

At that time, the young man next to the marshal’s mansion was still physically disabled and had his feet deep in the mud. Yao Zhi stretched out her hand and tried to help him, but the boy, who looked fierce, shut his eyes and was heartless. Yao Zhi has been the white moonlight of all young men in Beijing since childhood. Her crescent eyes were curved, and her beauty was incomparable.

Shen Xu regarded her as a god in his heart and never dared to put her in the bottom of his heart.

He looked up at the gods on a bright moonlit night, never thinking that one day she would take the initiative and rush into his chest. Yao Zhi, who became the pinnacle of his two lives, grabbed his clothes and said quietly.

“Shen Xu, if you ignore me again, I’ll kiss someone else.” Shen Xu couldn’t suppress his youthful emotions. He held the god’s waist tightly. He had no choice but to beg her repeatedly. “Zhizhi… “

“Don’t leave me,” she said, knowing that he was young and humble and that he had feelings as deep as the sea for her.

She wouldn’t leave. She would be the apex of the young man’s heart and stay together with him.
