Makie Sugiyama, Mai Nagao, and Ikuyo Tonegawa They form a trio of single women who are still looking for "Mr. Right". Makie is the most aggressive of the three; always targeting married men – she does not want to get "tied down" – she constantly tries to seduce Makoto, with little to no success.

Step Up Love Story
Makoto and Yura Onoda are a newly-wed couple with zero sexual experience. Yura is a shy and naive 25-year-old woman whose good looks grab men's attention, something that she dislikes because she gets embarrassed very easily. Her husband Makoto is of the same age, but as opposed to his wife, he loves having dirty thoughts about other women. Physically though, Makoto is truly faithful to Yura. Both of them may be virgins, but now that they are married, they are ready to dive into the world of sex, "practicing" as often as possible. However, the world of sex is complex, so they need all the help they can get to find their way through it. Thankfully, their friends, acquaintances, and porn media lend them a helping hand.
