What is the relationship between Keren and Ba Zhongying?

Ba Zhongying and Keren are husband and wife. The two characters in Li's works, Yachong Sakura, lived in a quiet village until a wandering nun and a crystal with terrible power broke this hypocritical calm. KINOMOTO SAKURA saved a nun Keren on the way to escape, but was infected by the broken crystal Keren carried and became a lawyer-like existence. But lovely fell in love with KINOMOTO SAKURA.

A summary of the story of Keren and Sakura

Yaeyama Sakura was born in Yaeyama Village. She is the eldest daughter of the contemporary Yaeyama shrine god. She has a sickly sister, Yaeyama, and she loves her sister very much. Because it hasn't rained for a long time in yaeko village, the villagers asked yaeko to hold a sacrifice and ask for rain from the fox spirit worshipped in the village. In the end, Yaeko chose Yaeko as a sacrifice and gave it to Yaeko Sakura.

Yae Chung-ming naturally didn't want his sister to die here as a sacrifice, so he secretly planned to take Yae Chung-ming away, but in the end, the plan was discovered. In order not to miss the auspicious time, Ba Zhongming held Ba Zhongming's hand with a knife and killed him. After the sacrifice, it began to rain, and the villagers shouted excitedly. Only Achongying knelt beside her sister Lin's body, and rain and tears mingled.

In the fourth year after her sister's sacrifice, Ba Yagura met Keren, who fled her fate with the black box and drifted to Ba Yayang Village along the river. Then eight Yagura took Keren to the shrine for treatment. After coming into contact with the black box, Ba Yang sang with the demon Fei Yu Pill in the box because of his hatred for the villagers, and Ba Yang was eroded into mimicry by Fei Yu Pill.

At night, Fei Prison Pill took control of Sakura's body and turned the mountain bear into a monster. Later, during the day, Sakura, as a witch, fought the monster alone, but eventually lost. Keren arrived in time, killed the monster beast, and saved Yachong Cherry Peach.

It's reprehensible for Ba Ying Zhong to face danger alone. After Ba Zhongying told the truth, worried about Keren's injury, and fought alone for so many years, Keren said that you won't be alone in the future, because I will fight with you. Ba Zhongying was deeply moved.

So regardless of the game, judging from the plot, when Yagura was young, his life was full of twists and turns, and his lovely feelings were even more touching. As for eight Yagura's seal being broken, that's another story. I wonder how Otto, the first green man in fate, feels about this.
