Today someone climbed over the wall to peek into their backyard; that meant their shop's business was booming and had already attracted the envy and attention of others.
Now that someone had come to spy, who knows if there will be others next time. Gu Ya instructed his young wife, "Yunjin, you must be careful when you brew the fruit wine again. Don't let others exploit any loopholes in the secret recipe of the fruit wine."
"Husband, I understand," said Su Yunjin. She certainly knew what to do—now that someone had spied on them, she would definitely be cautious and meticulous the next time she brewed wine.
The little incident quickly passed.
Su Yunjin didn't dwell on it further.
She had Gu Ya buy more grapes, green plums, loquats, and other fruits. Planning to brew several batches of fruit wine with them, she busied herself in the backyard.
