Forum: Story Recommendations

I read a story a few months ago about a kid who got the memories of a past life who happened to be a bi-woman and as result he knew he didn't like guys. That isn't the point of this request. I'm looking for stories where the mc uses memories of a past life to benefit his current life. Bonus if there is a male mc and a harem

Past lives

Technically do-over stories with time travel would fit the request. Several of them include harems.
