Tohru is confused and in deep trouble. After a certain incident with Takafumi, a senior high school student, Tohru can't get him out of his head. Tohru swore he would wait until Takafumi is legally an adult before doing anything sexual with him.

However, both are finding it hard to keep their urges under control. As temptation grows, the line between boy and man becomes conveniently blurred, testing their resolve and their feelings for each other.
