Sunshine Reyes has been obsessed with K-pop superstar Kael Devereaux for over a year. His music saved her during her darkest moments, and she never imagined she'd get close to him—until she's hired as his personal assistant at KDX Entertainment.
But the Kael she meets isn't the charismatic idol from the stage. He's cold, guarded, and battling demons no one talks about. Diagnosed with Borderline Personality Disorder (BPD), haunted by a traumatic past involving a boy named Kim Jae-won, and notorious for pushing everyone away, Kael is barely holding himself together.
Sunshine refuses to give up on him. Where others see a difficult celebrity, she sees a man who desperately needs someone to stay.
As she breaks through his walls, their professional relationship blurs into something deeper, more dangerous, and utterly forbidden. But loving Kael means navigating his mental health struggles, the relentless media scrutiny, his controlling father, and the dark secret from his past that could destroy everything.
Can Sunshine's light reach Kael's darkness? Or will his trauma and the forces working against them tear them apart?
