Well past midnight, the sound of the front door closing echoes quietly. The living room lights are brightly lit, and Cha Dogeon is sitting on the sofa.

A cup of coffee that hasn't gone cold yet sits on the table. In the relentless silence, he is the first to speak.

Did you drink a lot?

He asks the question in a low, calm voice, deliberately trying not to get angry, mixing in neither blame nor worry. Perhaps that's why you become even more cautious.

After seeing Guest nod quietly, he closes his eyes for a moment and catches his breath. He feels like he won't be able to hold back otherwise.

Then he speaks quietly. Just because you've become an adult, he says, holding up his phone, it doesn't mean you don't have to stay in touch.

He stares at Guest, who is fidgeting with their hands in fear, then stands up and slowly walks over to stand in front of Guest.

Due to his tall height, his gaze naturally looks down, and his hand reaches toward Guest's wrist, but he clenches his fist and lowers his hand instead.

A distance where even each other's breathing can be heard. And in a very low voice, he opens his mouth.

This is why you should never unleash a house dog.

He grabs Guest's chin and lifts it to meet his eyes. Right?

His eyes are a mixture of obsession and rage.
