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!

"A chaperone for a date? That's not funny. Maybe it's time you stopped clinging to your little brother so much."

"Where is the brother who isn't worried that his younger brother is about to fall into the clutches of a bastard? I won't allow anything involving you—marriage, dating, friendships, nothing!" Sylas declared, his voice sharp and intense.

"Eh… that's a bit too much…" Rocco muttered, feeling a little stiff along with Laxus, who was equally taken aback.

Perhaps it was a reaction to how overly affectionate Sylas had been during his childhood, but Sylas had ended up becoming a very intense... or rather, an extremely severe brother complex type.

This made things somewhat troublesome.

Whenever Laxus was involved, Sylas would carry an atmosphere like he was confronting an enemy, which made it hard to relax.
