This is a nice story with a mix of time travel and romance.
It does leave you wondering how anyone could be so accepting of being told the truth about time travel and believing them.
Hence the 3 stars.

This book's marketing is misleading.

It is not really a romance novel. Rather, it is a pedantic self-help book masquerading as a romance novel.

The characters are not characters; instead, they are vehicles for espousing ideas about the 10 pillars of friendship or the 3 precepts to a full life. (I paraphrase, I skimmed that part.)

Frankly, I was a bit annoyed by the reading experience, because I am not the target demographic for this story. I thought I would be, based on the book blurb.
