Shi Xu's Marriage Contract

Mother Shi said, "It's not a relationship."

Shi Xi lay back on the sofa in disappointment.

"They're getting engaged next month," Mother Shi added.

"Huh?!" Shi Xi sat up in shock again.

Mother Shi explained, "When your grandfather joined the army, he made an agreement with his comrades that if the child was a boy and a girl, they would become in-laws."

Shi Xi interrupted, "Then why are they separated by a generation? Are all the children born male?"

Mother Shi said, "...Later, they were sent to different places to fight, and there was no news of each other. This agreement doesn't hold."

"Just last month, your grandfather and that comrade met again. "He has an unmarried grandson, and that comrade has a single granddaughter."

"The two of them chatted for a while and decided to continue the agreement."
