Rocco Di Malvento lived a short, but loving life in his previous world, surrounded by a caring family. Despite suffering from a terminal illness, he found solace in books, especially his favorite BL novel >. But when he dies, he wakes up in an unexpected new life—as the weak, neglected second son of a powerful mafia family. 

Now reborn in the world of the novel, Rocco finds himself in a terrifying situation: he's the useless younger brother of Sylas, the main protagonist, and likely doomed to die young unless he changes the course of his life. So, what's his plan? Simple—befriend the protagonist, avoid being a spoiled brat, and secretly recruit Sylas's future allies to protect him. 

First target? Georgio the Hyena, an infamous killer. Rocco's strategy: charm the terrifying man and make him his ally instead of Sylas’s. 

It's a ridiculous plan, but hey, at least Rocco is trying. Can he survive the mafia world and avoid his tragic fate? He hopes so. After all, he’s just a kid trying to make the most of his second chance!

However, he hadn't expected anyone to notice his presence.

To think there was someone sharp enough to sense him… Such was the prowess of the infamous "Georgio the Hyena," once targeted by Del Fiore himself.

Yet even someone of Georgio's caliber couldn't withstand the raw aura of a Beastman.

Like the lion Beastman earlier, Georgio had collapsed the moment he was exposed to even a fraction of it.

"…Well, hello, Olgert. Turns out sneaking in was easier than I thought," he murmured, holding a pendant-shaped magic crystal close to his lips.

Leaning against the railing, he gazed back into the room.

His eyes fixed on the boy sleeping peacefully on the bed with a serene expression on his face.

The crystal shimmered, and an irritated voice crackled through.

"Hey, you brat! Are you pulling this stunt again?! Did you even tell the boss about this plan? The man's furious—he never gets this mad!"
