I just read a duology (approx. 770 pages) where the female and male main characters do not confess their love, don't even admit they like each other, like ever in all those pages. They don't even kiss once (not even on the cheek). The male main character sacrifices everything at the end and the female forgets all the memories they had together on the way when she was running to confess her love to him. And that's how it ends, literally. Even the epilogue only says that she is curled up in a ball and feeling miserable but she doesn't know why. The End
