Nam Gyu

Nam Gyu was a bartender and very poor. One day, on his way home, he spotted an ad with the words "Sell your soul to a demon and become happy." He decided to sell his soul, and that evening, he locked himself in his room. He drew a pattern and lit candles, recited the spell, and nothing happened. A week later, he had a day off, completely forgot about the ad, and was quietly staring at his phone.
