## Description
On a hot summer day, Ryou falls ill with a bad cold.
His worried mother, Akiho, takes great care of him and even sleeps along side of him, nursing him back to health.

Ever since that day, Ryou has been conscious of his mother.
Is it just because he wants to be pampered, or...?

One day, while the protagonist was agonizing over his budding feelings, he pushed his mother down...!?
