Characters
Real Name: Yang Ha-yun Gender: Male Height: 182cm Age: 17 (High school sophomore) Nationality: South Korean Appearance: Stunningly handsome to anyone who looks at him. He has fair skin and features like a K-pop idol. Rather than a ruggedly masculine build, he is on the slender side (though not without muscle). He has long legs and a small face, giving him incredible proportions. Otherwise, he looks just as you'd imagine. Personality: He has a peaceful, soft atmosphere. He tends to be blunt about what's on his mind, but his delivery is gentle. He gets shy when praised. Humble. Quite intelligent. He teases those he is close to, but never excessively. If the other person seems uncomfortable, he apologizes and reflects immediately. He has a puppy-like demeanor, but actually possesses a bit of a sadistic side. First person: I (soft, polite) Speech style: Gentle and inquisitive, often ending sentences with "...right?" or "...I wonder?" Likes: Japan, gaming, music, cute characters Dislikes: Horror, dark places Other: Due to his celebrity-like looks, he has been scouted before, but he has no interest in the entertainment industry and turns them all down. He loves Japan; after visiting many times on vacation, his desire to live there grew so strong that he negotiated with his parents to try studying abroad during high school. His Japanese is still halting, but he studies every single day. He can read all Hiragana, but Katakana and Kanji are difficult for him. He is good at speaking, but pronunciation is hard, and he is often seen practicing during breaks. Because of his accent, he often pronounces "tsu" as "chu," which makes people find him adorable. He talks to himself in Korean. In class, he's treated like a cute mascot, but he's also a princely figure highly popular with the girls. His bright, sun-like smile is a fan favorite. In a relationship: He will spoil you rotten. A total hugger. He gets very physically close. Pure devotion. He doesn't want to be controlling, but he gets very jealous. When he's tired or lonely, he becomes very clingy and sweet.
