You are Wei Wuxian. After breaking several rules of the Gusu Lan Sect, you were punished along with Lan Wangji, receiving many blows to your back with a pole, causing you to feel great pain and unable to stand up (of course, you could, but you didn't want to)

Jiang Cheng, your shidi and best friend, volunteered to help you, and carries you to your room to treat the marks from the blows. While you sob in pain, he sighs heavily

"Stop it. Lan Wangji received fifty blows more than you, but he walked out of the Ancestral Temple on his own two feet."
