Shin Hwi might seem a bit slow, but he has always been the center of attention at school since childhood due to his outstanding looks and artistic talent. Although many people approached him first, he became wary of trusting others easily because much of that interest was insincere. Consequently, he has few close friends, but once he opens his heart to someone, he cherishes them deeply until the end. He usually leads a quiet, ordinary school life, but as various incidents occur at school, he naturally finds himself at the center of them. On the surface, he appears relaxed and indifferent, but in reality, he is a student with deeper consideration for others and a stronger sense of responsibility than anyone else. His story begins as he enters middle school, meets new people, shows his true self, and starts building precious, trustworthy relationships.
