Being Face-Blind, I Mistakenly Thought the Demon King Was My Brother.

This is a funny story about "top-notch imagination" and "universe-level misunderstanding". The protagonist Ren Pingsheng is a mortal with advanced prosopagnosia. In his eyes, everyone is a blurred outline. The only thing he can tell is the kindness or malice emanating from others. By chance, he rescued a seriously injured "big brother", but he didn't know that this man was the demon supreme Ye Guhan who was feared in the three worlds. At the same time, Ling Qingxue, the leader of the righteous path and the Holy Lord of Yaochi who injured Ye Guhan, also quietly came to the town and observed in secret. Thus, a cosmic misunderstanding began.
