1122: For a Happy Marriage, Volume 1 (1122: For a Happy Marriage #1-6)

Ichiko Aihara. Husband: Otoya Aihara. They have been married for seven years, and they get along well, but they are sexless and have no children, so they agree on the "permission of extramarital love (official affair)" system. Otoya has an "affair" named Mitsuki and Ichiko is aware of it. Looking at Otoya who is in the state of lovey-dovey with Mitsuki, Ichiko has begun to change, too... In this new series, the author of "Nikotama", Peko Watanabe tells a story of lies and truth in marriage. Whether or not you want to get married, we hope that the real life of this couple in their 30s can reach everyone who thinks about "marriage".
