- Description from Novelupdates

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.

‘I died and became an extra in a male-dominated fantasy novel. The only problem was, I hadn’t read the novel to the end. One thing I do know is that a terrible future awaits me, and thus, I, now Dalia, have decided to live a safe and prosperous life for the rest of my time here.

Since I don’t know what will happen, I will be a bystander observing the main character from the sidelines… I’ll make my own happy ending away from the main plot!’

With that determination, Dalia embraces the role of an extra. And like all extras, she clings to a golden thigh: Kaichen, the powerful wizard who is unwaveringly loyal to the protagonist.

For Dalia who wants to have a happy ending, it was imperative to extract herself from the novel’s plot… Yet her calm life is shaken when a flirtatious romance begins to bloom between her and her golden thigh.

Will she be able to resist the temptation?
