Summary

A brief description of the manhwa The crazy son-in-law of the Grand Duke of the North:

Galahad is an elite mage serving in the Intelligence Bureau. For political reasons, he is practically sold off to become the live-in son-in-law of the Northern Grand Duke. The ice-cold Grand Duke’s daughter is actually the “key to defeating the Demon King and saving the world.”

Determined to win her heart, Galahad approaches her the only way he knows how—with his usual logic-defying madness and unstoppable drive. There’s just one problem: she’s a Swordmaster who burns mana. For a mage like Galahad, even holding her hand means enduring excruciating pain that shoots through his entire body…

“I want to touch her again. Next time, for a little longer—.”
