When Shota and Kenta's mother started working, a babysitter came to their house. At first the two complained, but then they were thrilled when busty Meguru showed up. The kind-hearted Meguru was bewildered by their pranks but responded with a smile... The realistic conversations and the gentle atmosphere of Meguru Kosaka, such as the close-contact pranks they played during hide-and-seek, the pranks they played in the bath, and the pranks they played while sleeping with their siblings, all add to the excitement. This is a masterpiece that was born by staying true to the basics while raising the bar in every aspect.
