Regarding the childhood marriage promises,
Xu Musen felt they definitely existed.
When he was a kid, he heard his parents joke about it, but such promises were usually just verbal and taken as jokes.
It was common for close friends to sit together, drink, brag, and on a whim become sworn brothers or promise their children to each other in jest.
Unless there was some written documentation, there wasn't much to it.
However, in this day and age, those so-called childhood marriage promises were long gone.
"It was all just childhood jokes. When I was a kid, I even said I wanted to marry Wang Zuxian, but matters of the heart are best figured out on one's own," Xu Musen said with a smile, shaking his head.
An Nuannuan gave an 'oh', with a slightly brighter tone, blinked, and then spoke again.
"I heard from my grandparents that they were paired up through a childhood marriage promise, and they're still living happily together," An Nuannuan said, nodding at him.
