If she were to settle down and fall in love with one of the girls in her harem, portraying that as a wholesome ending with positive character growth would be pretty fucked up since they would never have gotten together without the mind control potion, so the fact that the manga says fuck that and just revels in the trash is best case scenario. The only positive ending i can imagine would be her getting arrested and all the girls losing their brainwashingThe MC is like the 'ugly bastard' character from NTR manga, however, not only did she deifile the girl but seduced her partner as well. On a more serious note, it's getting a little hard to empathise with her because there is no character growth. I hoped that she would grow as a person, learn her life lessons, and get attached to the girls who are into her. But alas, this is a trash-tier excellent gag manga.
