10 years ago, after “the Gate” that connected the real world with the monster world opened, some of the ordinary, everyday people received the power to hunt monsters within the Gate. They are known as “Hunters”.

A car accident left Mu Lan, who was about to get a divorce, with sudden amnesia.Gazing at the strange man before her claiming to be her husband, Mu Lan was speechless. Could her taste really be that terrible that she chose a man with a poker face?“Whether I was blind or out of my mind before, since the heavens have granted me amnesia, this is an opportunity to start anew.So, this marriage, I'm definitely ending it!”However, no one can escape the so-called 'True Fragrance Law.'Not only did she fail to get the divorce, but she also ended up investing herself into it....Tingxiao never expected to suddenly find charm in the woman he had married for seven years and hardly bothered to look at more than once, all because of her amnesia.But even though they had agreed that once her family overcame their difficulties, they would go their separate ways, he found himself unable to let go.“Tingxiao, you're shameless, breaking your promise and growing fat from it.”“If I'm fat, I'm fat; for my wife, I accept it!”

After his parents died, Alex Roth had a plan: become a wizard. Through hard work, he was accepted into the world’s greatest university of wizardry—but fate had another plan.

On his eighteenth, he is marked as one of his kingdom’s five Heroes, chosen to fight the land’s great enemy. But his brand is 'The Fool', worst of the marks.

Rather than die or serve the other Heroes like Fools in the past, he packs up his little sister, his childhood friend and her cerberus, then flees for the university in hope of refuge, magic and to unravel the truth about his land’s evil.

There’s one small problem: The Mark tries to ruin magic while enhancing skills outside of divinity, combat and spellcraft.…

…that is, unless he can learn to exploit the hell out of it.
