Second Trip to Watashi no 7-nin no Otto-tachi ni Tsuite

A year ago, the protagonist entered an alternate world where she ended up doing housework for students at Adergart Knight Academy rather than forming romantic connections. After returning to her original world, she came back a year later to discover that ten years had passed in the other world. During that time, a significant drop in the female birth rate led to the introduction of a multi-husband system. The young men who had not married in her absence are now pursuing her. The narrative involves themes of unexpected relationships and a reverse harem dynamic.
