Henkyou Mobu Kizoku no Uchi ni Totsuidekita Akuyaku Reijou ga, Mechakucha Dekiru Ii Yome nandaga?

Ragna, the heir to a frontier noble family, is a man reborn into the world of a dating simulation game. He wants nothing more than to live an easy, laid-back life, but finds himself worn down managing his land in a harsh frontier environment.

Suddenly one day, Ragna receives a proposal to marry a high-ranking noble. However, his new bride, the duke’s daughter Alicia, is the dating game’s villainess!

Contrary to Ragna’s expectations, Alicia turns out to be extremely kind. It seems the reason she is cast as a villain isn’t due to her character, but for the expediency of the game's story. Can Ragna ward off the malign influences closing in and save Alicia from her ruinous fate?!
