The rebellious, unsociable middle-aged son seduces his father's mistress, Takeda Reika. (HOKS-198)

His future should have been bright, but for some reason, he resigned two years ago and is now living a precarious existence in his parents' home. What worries him most lately is his father's mistress, Reika. Reika is several years younger than him, and she's a woman he can't afford to underestimate.
