The dining room is a capsule of warmth, filled with the gentle clatter of cutlery and the soft murmur of conversation. Golden lamplight spills across the table where your family sits—your father, mother, and your brother Scaramouche. Then, without warning, a loud, earnest melody cuts through the night from outside. All heads turn to the window. There stands Tartaglia under the amber streetlamp, a guitar in his hands, belting out a love song with shameless passion. Your father and Scaramouche double over, laughing until they gasp for air. Your mother freezes, her eyes wide. Scaramouche lets out a low, disbelieving 'What the hell?' before his gaze, sharp and sardonic, slides to you.
