After Binding the Yandere Prince, My Waist Is a Little Too Sore

Xu Ji is chosen by the Weak Bottom System and transported into a book, where he falls in love at first sight with the book's villainous big boss.

"System, can I tie him up and take him home?"

"You can't!"

"Then can I lock him in my room?"

"You can't!!"

System: "Host, wake up. He's not the male lead. He's the book's biggest villain, the Second Prince Wen Ruyu."

"Oh, I see."

Just as the System breathed a sigh of relief, Xu Ji spoke again. "Then can I kill them all?"

"You can't!! What kind of demon are you?!"

The System was on the verge of a breakdown. It was all because he'd been young and naive, all because he'd judged by appearances. Who could have guessed that this Host was a wolf in rabbit's clothing!
