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!

The first person to check inside had been that very sentry.

It was also him who quickly identified the owner of the "contents" and discovered that they had since gone missing.

Sylas turned to get a look at the gatekeeper in question.

Recognizing the man as one of the elite assassins under Georgio's command, he understood why the situation had been grasped so quickly.
