Haneureseo Cheonsa-ga Naeryeowa Haneun Mal

Soo-Hyun had been treated as a monster due to his white hair and unusual green-blue eyes. Everything about him was not normal which led him to live as a loner. Then one day, an angel named Noah unexpectedly came down to his room and talked to him. “I’ll cure your erectile dysfunction.”

Unfortunately, instead of getting cured, Soo-Hyun got a side-effect in which he got an erection regardless of the time and situation due to the angel’s lack of power. Unaware of Soo-Hyun's embarrassment, Noah just smugly said “Now, let’s show them how beautiful monster you are.”
