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—.”

Untitled review

I have completed the novel ending at chapter 397 and it was a good read (8/10). The same author as the novel/manhwa "The Roguish Guard in a Medieval Fantasy". Romance with action produced by Redice Studio make the hype for this manhwa even more! Looking forward to this very much as a fellow novel reader 😄

Not Bad Not Bad

Honestly given the title I think most people probably pushed it off as some bs. But it isn’t heavy on the romance and I do think it has some potential. Is it great, no … but it’s not bad either.

Full of cliches, dropped already

This is a trash comic which will continue the boring trope of everyone hating him for 50+ chapters until he saves her life. Later he will join the North in the fight against Empire, and marry the princess. The outright hostility in these chapters is cringe and needless. "The Dragon Bride" did it better in that regard. I know what will happen to this manhwa after 100 chapters, it will get mediocre just like so many of them did became previously, I can see it already. Dropped after reading first 6 chapters, because...
