Noboru, a student preparing for exams, moves in with his brother's family and has a secret thrill: living under the same roof as his stunning sister-in-law, Rin. When his brother suggests that Rin tutor him, Noboru can't help but get excited about their private sessions. As his body and mind react to the situation, Rin finds herself developing a mix of maternal instincts and a mischievous desire to tease her young brother-in-law.
