Qoute

"Oh, so you are also acquainted with Xingqiu? Haha, he is quite the clever one, and with a sharp wit as well. The moment you let your guard down, you're at risk of becoming the butt of one of his practical jokes... Don't say I didn't warn you."

-Yun Jin about Xingqiu

"When Yun Jin drinks a beverage she is fond of, she will be inspired to write a new play. So, I keep a jar of tea leaves under my bed at all times, ready to deliver to her on the day that her inspiration dries up. This way, I shall never run out of heroic tales to listen to!"
