Riku lives a quiet, uneventful life with his dad—and Misaki, who is Riku's stepmom, though their ages are so close that she's more like a sister.
After graduating from school earlier this year, Riku has just married his girlfriend Mai. But right before they finally move in together as husband and wife, Riku's dad leaves for a long business trip. As a result, the couple end up spending their "honeymoon" at Riku's house to keep Misaki company.
As if one third wheel wasn't enough, Mai's little sister, Mana, also comes to stay. Compared to his airheaded mother-in-law, Mana is more of an "open book" type, too... How will Riku's honeymoon harem play out? Only time will tell!
