Monaka, an honor student studying at a preparatory school in Tokyo, is a serious student with a strong sense of justice. He has excellent grades and is also the class president, planning to enter a famous university after graduation. One day, as the class president, he brings prints to a closed student's house, but it has become a hangout for bad students, and cigarettes and bleach are rampant. Of course, "Monaka" cannot ignore it and warns her, but... The serious and innocent class president was played by paranoid guys until his personality collapsed. A work that captures the ecstasy of the immoral feeling that such beautiful things are unreasonably tainted.
