Lingyin Ties the Knot for Three Lives
Shang Si always thought that her time with Nezha had been nothing but a dream. She never expected him to tie her up with the Red Armillary Sash on the battlefield, cover her with a piece of red cloth, and keep pressing her down until she bent over.
What is wrong with him?!
Nezha loves flamboyant red robes and wears red no matter the occasion.
Since people wear red when they get married, his aunt told him that she and Prime Minister Jiang had worn red at their wedding, and so had Tu Xingsun.
The next time Big Sister appears, he can marry her right away. He'll tie her up with the Red Armillary Sash so she won't get lost.
