Title: who's your daddy ? (Alt Title: My Stepdad is a Mafia Boss!?) --- Tagline: "He was supposed to be my protector, not the man I dream about in the dark." --- Summary: Eighteen-year-old Elliot Hayes always kept to himself-quiet, obedient, and invisible. After his mother's divorce from her mysterious, terrifying husband years ago, Elliot barely even remembered the man... until the night he was shot walking home from his part-time job. He wakes up, bleeding and confused, in a lavish mansion guarded like a fortress. And sitting beside him-dressed in all black, tattooed, sharp-jawed and cold-eyed-is none other than Viktor Moretti, his 34-year-old estranged stepfather... and one of Europe's most feared mafia bosses. Elliot's world turns upside down when he realizes he's not just being protected-he's being kept. With his mother out of the picture, and his enemies unknown, Viktor declares Elliot will stay under his roof until it's safe. But Viktor isn't the cold-blooded monster Elliot imagined. He's powerful, yes. Dangerous, always. But also quietly attentive. Overprotective. And behind those cruel eyes lies a longing neither of them dares to name. As the walls close in and the bullets start flying, Elliot finds himself drawn to the one man he shouldn't want-and Viktor? He's beginning to wonder if protecting Elliot was ever just about keeping him safe... or something much deeper.

Ryu Seo-woo is an award-winning best vocalist who tragically died in a plane crash and transmigrated to a BL novel, "Serenade Me, My Angel," which he read out of boredom. He transmigrated into the body of the sub-villain, who shares his name but is a C-list singer with a ruined voice due to throat damage. Living in a decrepit house with his five-year-old triplet sons (Seo-jun, Seo-min, and Seo-jin) who despise him for years of neglect and verbal abuse, Seo-woo is determined to rewrite their lives. The novel's main couple, the stoic CEO Moon Woo-seok and his innocent, angelic singer Jin Yu-jin, are destined for a happy ending. In the original story, Seo-woo's character dies in a fire, leaving his genius triplets to be adopted by the main couple. However, the transmigrated Seo-woo has no intention of dying or letting the original plot play out. Can he win over his sons and forge a new path?

"What kind of creep are you? Stalking your own cousin?" Wonwoo looks up from his phone to see a tall man, dressed in basketball shorts and a jersey, his face flushed and breath heavy. "Sorry? Are you talking to me?" Wonwoo asks, pointing at himself. "Yes! You! Stop stalking Jia. Stop stalking my girlfriend!" Wonwoo freezes, his hands gripping his phone tightly, before he lunges forward, throwing his fist right into the other boy's jaw. "Why the hell are you referring to my girlfriend as yours?"
