Summary
The one where Roy and Jaime are stepbrothers.
“Oi, listen up, cuz I’m only going to say this once.” Silence fell over the room and all heads turned to Roy. His index finger pointing towards the players to emphasize the seriousness. “Anyone who talks about this ever again gets headbutted. If this winds up in the Sun tomorrow and I find out who talked, I will cut off your balls, roast them with a nice glaze and then feed them back to you. Got it.” There were nervous nods of agreement.

A soft voice is cleared behind his soon-to-be-ex-stepmother, and he remembers, finally, why they're all supposed to be so serious about this.

He's far too old for this.

Summary
Hyung-suk, un talentoso productor musical que se oculta tras la identidad de “Eon”, lleva una vida dividida entre el anonimato y la fama ajena. Nadie sabe que él es quien ha creado los mayores éxitos de Taeyeon, su madrastra, y de Minjeong (Winter), su hermanastra. Desde que su padre se casó con la reconocida líder de Girls’ Generation, Hyung-suk convive con ambas, intentando mantener una distancia emocional que pronto se vuelve imposible.
Taeyeon, con su serenidad y madurez, despierta en él una atracción tan intensa como culpable, mientras que la dulzura y vulnerabilidad de Winter lo envuelven en una ternura que también se convierte en deseo. Atrapado entre dos amores imposibles, Hyung-suk lucha por contener sus sentimientos y proteger el secreto que podría destruirlas.
Cuando la verdad sobre “Eon” comienza a salir a la luz, el equilibrio entre los tres se quiebra. En medio de la fama, la culpa y las emociones prohibidas, cada uno deberá decidir si seguir el camino de la razón o rendirse a lo que el corazón dicta. Una historia sobre amor, música y las fronteras difusas entre lo correcto y lo inevitable.
