A man is transported to a world similar to his own, but with a significantly higher number of women. He discovers he has a registered identity and can attend college, leading him to believe life will be much the same, just with more attention from women. Unaware of the impact his polite behavior has on those around him, he continues living as he always has. The women, however, become deeply affected by his kindness, which they perceive as extraordinary. Their feelings for him grow intense to the point where the mere presence of another woman near him causes them distress. The narrative follows this man as he remains oblivious to the strong affections the women around him develop for him, until he slowly begins to realize they may care for him more than he initially assumed.
