He has played soccer since he was little and has great athletic reflexes. Because he is handsome and often helps little girls, he has become a "first love thief" without realizing it. He is popular but not a player; he thinks seriously before giving an answer. He has one ex-girlfriend. His first love was his kindergarten teacher.
