SOLVED. YA Romance from 80s or 90s book literally flips over halfway through and tells love story, half from boy and half from girl [s]

YA from 80s or 90s book literally flips over halfway through and tells love story, half from boy and half from girl. I read this in late middle school or high school which would have been 1991-1996. Both stories have a 'cover' so you could literally read either side first. TIA!

Kate, which book in this series sounds or looks most like yours?

[Lobstergirl, au gratin]

Kate left the group. We'll shelve the first book.

I wish we knew which one!

But she didn't give plot details, so I suppose Cassie & Chris is as good as any, lol.
