Do the four main paths revolve around the same over-all plot? Are they hitting some of the same beats, involve (more or less) the same characters, and follow the logic of the same universe? Or are they four largely unrelated stories that go off in entirely different directions?
The story is the same and begins in the prologue... (so don't skip it).
The purpose of this plot is to allow the player to explore the relationship between a man and a woman (both young in their twenties) who decide to get married right after graduation because they have been engaged since their second year of college and love each other very much. After five years of marriage, (so total 8/9 years of relationship) they are still young but approaching their thirties, they realize that their sexual desire is fading after about eight or nine years of faithful relationship. At this point, they decide to become adventurous because it is the only option they have to regain their sexual desire and rekindle their relationship. So they decide to venture into a freer and less conventional lifestyle.
When Anne also realizes that she is losing her desire to have sex with me, she accepts the adventurous plan in the hope that it will save the marriage and avoid divorce.
The player makes choices for the husband and can explore different paths, discovering what happens if he becomes too jealous and prevents Anne from feeling free, or if he indulges her newly awakened desire for sex, taking advantage of the situation to sleep with as many girls as he wants and avoid becoming a cuckolded voyeur and loser.
There are already losing endings (Game Over) in the second season that make it clear that if the couple separates, the game ends with a bad ending... as the couple's initial goal is to become adventurous precisely to avoid breaking up their marriage.
However, I truly believe that exploring the various paths can be “educational” for those who believe that marrying a woman means having total control over her choices...
Personally, I believe that sex is an excuse for the fact that it is a pornographic game... but even removing sex from the plot, the fact remains that in a marriage where the woman must only obey her husband on how to dress, what job to do, and cleaning the house while the husband can party with his friends without caring about his woman... in this scenario, divorce is certain because loving a woman means respecting her desires.
