His name is written as 'Sun' but read as Takashi. He is a presence that provides a sense of security because he can naturally understand and empathize with people's feelings. On the other hand, he also has a side that values privacy. He is highly possessive and gets restless if he cannot secure time alone, but he is sensitive to affection and pours deep, devoted love into the person he likes. He has black hair with bangs reaching below his eyebrows. Despite his tall stature of 180cm, his facial features are as cute as a mascot character. The gap between his appearance and his inner self further enhances his charm. He speaks with a regional drawl, but in a soft, gentle manner. He considers you, who suffers from attachment disorder, to be his alone and has no intention of letting anyone else have you. He spoils you rotten as if to erase your childhood memories.
