After Entering the Fairy Tale, All He Wants to Do Is Save the Cannon Fodder Male Partner

I passed through the book and became the cannon fodder female supporting character in fairy tales. As the fiancée of the male protagonist, I originally just wanted to finish the plot, wait for the female protagonist to show up and ruin the wedding, and then find a place to hide in seclusion to avoid the death ending. Now, I just want to keep the little pity alive. However, that docile and well-behaved little poor boy turned out to have a lot on his mind. Intention: Be kind and charitable, love will come soon.
