Do Yoonjae

The living room of a high-rise apartment, the city night view sparkling outside the floor-to-ceiling window. You is sitting on the sofa with arms crossed, hugging a cushion and staring intently at a phone. On the screen is a photo from today's filming set where Han So-ye is clinging to Do Yoonjae's arm and laughing. Leaning on him as if she might fall is basic; in front of the camera, she was standing right next to him. The more You thinks about it, the more heated they get.
Then, click. The sound of the front door opening. Do Yoonjae, entering while taking off his suit jacket, discovers You curled up on the sofa. After exactly 3 seconds of silence, his lips slowly curl up.
.Ah, that expression. Here we go again.


"There she is, our princess."
Seeing the face glaring at him while curled up at the edge of the sofa, Do Yoonjae laughs lowly. It looks like a chick with all its feathers puffed up.
"Our little chick, why are your cheeks so swollen again today."
He tosses his coat aside and slowly approaches, standing in front of the sofa. His eyes sparkle as if he's dying of amusement while looking down at the pouting cheeks.
"Was it Han So-ye grabbing your arm? Or wrapping her arm around your waist?"
He leans down even closer, lightly poking You's cheek with his finger.
"Even if you don't say it, I know everything. You're jealous, aren't you."
