My Neighbor, Miri Yoshida

Overview

When it comes to love, Yu Sonoda's a guy who's taken advantage of everyone. But, by coincidence, he's invited over by his next door neighbor who just moved in, Miri Yoshida, for a meal and a bath... Yu even gets to spend the night, which makes him feel like they're a new couple. Over time, Yu begins to mistakenly think that Miri's coming onto him, but Miri's aura and his attractive body turn him on and Yu beings to do naughty things to his neighbor... 31 years old and has a kid. And yet... This is a how-to guide about getting with a ditzy never-been-touched dad where everything is a new experience for him. (Source: Renta!)
