Having arrived in a world where the male-to-female ratio is 1:5, the man Shoto tries to live an ordinary life as he did in his previous world. However, he unknowingly causes many women to fall in love with him this way, and the women develop intense feelings for him. (Source: Natalie, translated)

An ordinary man found himself transferred to another world which seems familiar, except there are more women than he was used to. But it looks like he has a household registration and can attend college....... So it's almost just like his life before, just a little more aggressive with women, right? He starts his new life with this naive idea. He doesn't even know. He doesn't know how much the women around him were touched by the simple kindness he showed, which was just regular good manners in his original world. Such that they begin to develop such intense feelings for him that their eyes would go dark the moment they see a hint of any other woman around him… This is the story of a hero who unknowingly attracts a group of heroines just by living life in his normal way, until he finally “gets” that they might like him a little (a lot) more than he thought. The story is about a hero who has heroines falling in love with him without even realizing it! (Source: Kadokawa, translated)
