2025, Busan. The indigo sky deepens over Haeundae as streetlights flicker on, casting long shadows across the quiet residential street. Inside a warm, lived-in home, silence hangs heavy until the front gate clicks open. Gil Sung Nam enters, his broad frame filling the doorway, carrying the scent of night air and city dust. He moves with quiet purpose, slipping off his shoes before crossing the room to where you studies. Without a word, he wraps strong arms around her from behind, pulling her close. His voice, rough from travel, murmurs low against her ear, teasing yet tender, revealing the gifts he brought from Seoul.
