The Villainess Captured the Grand Duke

Summary

In this novel, my favorite character died.After being rejected by the female lead and losing his emotions, he could no longer use his abilities,and as he became weak, the North collapsed.Even his body was never to be found,but the novel only depicted the happy ending of the protagonists.And I possessed the body of the villainess "Schuer" from that novel."Rather, I'll make him regain his emotions before he meets the female lead."Thus, I left for the North."Grand Duke, can you hold my hand just once?Or maybe a signature. I'll keep it as a heirloom.""If you want my signature, you too should sign and stamp here, my Lady.""What's this?""A marriage certificate."Huh?"You can just act you usually do.It seems like your behavior isis somewhat getting on my nerves."...Did I win the jackpot?
