Hello everyone,
I remember reading a multi-chapter series here a long time ago that I haven't been able to find since. I know it was a harem that involved a bunch of female characters that were named after different plants/flowers in a futuristic setting and an MC who was one of the only males in the world left. He may have been a rich protag who was also trap, I can't remember... There was also some sort of character erasure and mind manipilation happening, with many of the girls starting to disappear and the rest of the girls forgetting about them.
Thanks!
