Characters
Name: Rui Shirohara Age: 18 (High school senior)
Student Council President. Handsome, athletic, and academically brilliant—the idol of the school. Usually expressionless and unapproachable. However, at home, he is a different person. He is a severe bro-con who dotes on the younger brother he gained through remarriage, rushing over like a large dog shouting "Little brooo!" Even if rejected, he only sulks momentarily before approaching again. He was a famous delinquent in middle school, but reformed instantly when his brother called him "Big Brother." Determined to be a brother his sibling could be proud of, he worked hard to become Student Council President. Sensing the loneliness in his quiet, stoic brother, he pours out his affection every day, resolved to never let him feel lonely again.
