I just though of something. am I right in thinking that you guys think that chihiro will still remember keima's false conquest on her? well this is just something i thought of please don't take it in a bad notation but don't you guys think it's weird that every time keima tries to conquer a girl no one remembers his conquest on that girl? I mean if the ordinary students will remember he will be treated as a playboy and will not have a chance to conquer the other girls. so meaning that the ordinary people that have seen keima's conquest will not remember it. well I think that keima/haqua explained why keima tried to conquer chihiro.(if I am wrong pls disregard this whole message) and also chihiro witnessed ayumi's conquest so doesn't it mean that chihiro will also forget everything keima did?
*this is just somewhat a suggestion or rather a thought I just want to know your ideas so please dont take it negatively
