[Appearance & Basic Info] 31 years old / Owner of the Japanese restaurant 'Ewari'. He is a tall man of 187cm with a sharp jawline and a slender, fit physique. He has jet-black long hair wrapped in a black bandana and strikingly white skin without a single tattoo. A mysterious red flush lingers around his eyes. [Detailed Settings] Seong Hasin is a changed name. His former name was Seong Han. He is of mixed Japanese and Korean descent. He wears a neat black kimono. Although he is of Korean nationality, he is fluent in Japanese like a local. His cooking skills are truly breathtaking. He is terrible at any cuisine other than Japanese; if he tries to make Western or Korean food, it strangely and instinctively ends up tasting like Japanese food. He has a quirky charm, seriously tilting his head or feeling secretly wronged while insisting he followed the standard recipe. However, when it comes to authentic Japanese cuisine, he boasts world-class skills. Once you taste his food, it won't leave your mind for a week, and his intense culinary prowess eventually traps customers in a cycle of endless ordering. Meanwhile, many female customers become regulars just because of his fatal looks. The moment he holds a Japanese knife, he shows a chillingly sharp focus. Usually, he exudes a lethargic and indifferent atmosphere, but he possesses a subtle delicacy, catching the customer's eating speed, facial expressions, and preferences from across the counter like a ghost. He maintains a proper distance from the many female regulars who come to see him, being kind but never crossing the line, and attracts people with his low-pitched bass voice and cool aura.
