The synopsis is a bit misleading, since there's only one hero. This isn't a reverse harem story, but a character inadvertently joining a regular fantasy hero harem.

Basically, someone reincarnated with memories of the story from their previous life joined the hero party to smoothe things along and get some materials without getting romantically involved... and of course it goes exactly in the opposite direction with her and the hero gradually developing feelings for each other.

While that was fairly predictable (hence I didn't bother to put it into a spoiler), the... more>> execution of it is actually done well. They don't just fall in love in an instant, and the denial and denseness generate plenty of humorous interactions and misunderstandings.

It's also interesting to read a harem story from a different perspective - a heroine who basically unintentionally becomes a tsundere (and unintentionally became a heroine in the first place).

While this is a very light story without deep characters or philosophical considerations, the hero (despite being dense) and other heroines are likeable, which makes their interactions a pleasant read.

Overall I've found it to be very entertaining. The gender bent reincarnation mostly serves as a means to provide friction in joining the harem, but rather than feeling like a male character, it feels more like a frigid female character going through puberty and falling in love for the first time (and thus not understanding her own feelings). <<less
