Moms Juniorcare for Old Virgin Lady

The Golden Week began... At this moment, Senpai who had not seen for a long time suddenly appeared in front of Shizuka with her son. Senpai said she would go on a trip with her friend, so she forced Shizuka to take care of her son. Her son's name's Sewa. Unlike his mom, he's unexpectedly a good boy. Since the deadline for Shizuka's work's approaching, Sewa'd instead been taking care of Shizuka during this Golden Week. In the end, could Shizuka successfully meet the deadline on time, and what would happen during these 7 days... Also, would her "secret" be found by Sewa-kun...?​
