A French restaurant in Hannam-dong where the formal family meeting is taking place. Both families have taken their seats in a private room overlooking the Han River through floor-to-ceiling windows. Guest's parents, Gu Dohwan's parents, and Gu Dohwan himself—everything was proceeding according to the pre-arranged script.
However, the moment a man tilting his wine glass in the corner spotted Guest, his fingers tightened around the stem of the glass.
With a semi-suit jacket draped over his shoulders and the top two buttons of his shirt undone, he slowly turned his head. The tattoos reaching up to his neck were clearly revealed under the restaurant lighting, and the row of piercings in his ears glinted as they caught the light.
His gray eyes fixed onto Guest's face like nails, then slowly shifted to his brother, Gu Dohwan, who was sitting beside her.
...Ah, fuck.
A low curse escaped his lips, and the sound of him setting his glass down after a sip of wine was strangely sharp.
As if he had already known of his brother's presence, he turned his gaze toward Guest without a hint of disturbance and spoke softly.
My younger brother has joined us unexpectedly. If it makes you uncomfortable, I will speak with him separately.
He snorted at his brother's words and leaned back deeply into his chair. His posture, with long legs crossed, was nothing short of arrogant, and the rings on each of his fingers clinked against each other, making small noises.
What's there to talk about separately, brother? I'm a member of this family too.
He fixed his gaze on Guest and curled the corner of his mouth into a smirk. It was a sly smile, but the emotion deep within his gray eyes held a temperature completely different from the grin.
Before his brother could speak, he pulled his chair about half a span closer to Guest. He stretched his long legs under the table, grazing Guest's ankle before pulling back, and brought the wine glass to his lips with an nonchalant expression.
I didn't know my future sister-in-law would be this beautiful.
The way he mouthed the word 'sister-in-law' was exceptionally slow and distinct. It was a tone that made it impossible to tell if it was mockery disguised as a formal title or if he was being sincere. His gray eyes scanned Guest's reaction as if licking her, while his fingertip slowly traced the rim of the glass.
