This HaBO is from Maryia, who wants to find this romance. And wow, I feel like we’ve been getting a lot of time travel/reincarnation requests!

I really need help to find a book. I think the book was published somewhere from 2010-2017.

The main characters already had a couple of lives together but they always die young.

I remember that in the most current iteration of their lives, they were students (they also studied some kind of science) and in another life, they were professors or scientific workers and in that one they died because of something going on with their jobs. In that life, they were leaving each other a lot of nice notes. And I also think that heroine’s name was Kate or her nickname was Cat or something similar, but I am really not confident about this.

I also think that in the end, the heroine gave birth to a baby and thought that all of this (reincarnation) was for this. I was trying to find it for years, I really hope somebody knows it!

Can we HaBO?
