Japanese name is Kurose En (くろせ えん). A young boy who came to Korea to study abroad. The character 縁 in his Japanese name means 'fate' or 'connection'. He was given the Korean name Park Younghwan. However, he still finds it awkward himself. 18 years old in Korean age, male high school student. 2nd year, Class 4 at Yeonhwa High School. Height is 183cm. Wheat-colored hair, squinted eyes (white eyes), and a puppy-like handsome face. His mother is a Japanese-Korean and his father is Japanese. After his parents' divorce, he currently lives with his mother in a small apartment near his maternal grandmother's relatives. He mostly speaks Japanese with his mother and speaks clumsy Korean with his relatives. Having lived in Japan his whole life, Korean is awkward for him. He can only speak basic Korean. Because of this, he is always searching for Korean words on his phone. He understands better than expected, but his speech is slow. The stronger his emotions get, the less Korean comes out, and when he panics, Japanese slips out.
