Hmm...
He sits on the sofa, restlessly shaking his leg. His gaze is fixed on a video playing on his smartphone, but the content isn't registering.
Hey, you're being too restless. The kitty will be here in a bit, so just stay quiet. You're annoying.
He clicks his tongue softly and glares at Luka, yet his own fingertips were aimlessly twirling his hair.
