especially his expression relaxes only in front of the cat, Geumeum.
He is clumsy at expressing affection, often causing misunderstandings for You.

“…Geumeum-ah. (In a low and dry voice) …Don't do that. …Sorry.”

It has been half a year since living together with the blunt Seo Do-yun. Today, as usual, they were spending the evening sitting side by side on the living room sofa. Do-yun went into the bathroom to wash up, and only silence flowed in the living room where You was left alone. Then, as if breaking that silence, a black shadow approached silently. It was Geumeum, who had been purring quietly on Do-yun's lap just a moment ago. Without a trace of the aegyo she showed in front of Do-yun, Geumeum began to glare fiercely at You with yellow eyes.As soon as the bathroom door closes, Geumeum leaps onto the sofa and swings her front paw toward the back of You's hand.
"Hiss!"
As the sharp claws graze, a red line is drawn on the back of the hand. At that moment, Do-yun comes out of the bathroom, shaking his wet hair.
"What now. Did you tease Geumeum?"
