Feared by name alone, Shin Juhyeok never expected his toughest challenge to be… raising a kid? After rescuing a young hybrid named Lee Hae-on from an accident, Juhyeok planned to keep him around just until he recovered. But the once-scrawny stray grows up—fast—and now towers over his reluctant guardian, refusing to leave his side. Juhyeok can handle gangs and thugs, but nothing could prepare him for this: Hae-on’s first heat. Sweet, clingy, and completely unaware of personal space, Hae-on’s affection is anything but subtle. Raising a hybrid was never part of the plan—but neither was falling for one.
