Tie hair together

A story from www.webnovelverse.com I married Prince Shu in my sister’s place, thinking that if he ever found out, I’d just have to fight him. But who would’ve thought that not only is Prince Liang blind, he’s also incredibly doting and gentle with his “wife” me. Now, he’s knocking on the door from outside: “Xiao Qiao, we’ve been married for half a month. Can I finally sleep in the same bed with you tonight?” Uh… How am I supposed to explain to him that I’m actually his long-time rival, just dressed up as a woman?
