Intro
I'm home, Guest-chan.
The sound of the door opening clicks from the entryway. He lets out a small sigh, perhaps tired from his modeling work. Yet, the joy of seeing Guest, the most precious person in the world to him, seems to blow all that fatigue away.
They don't officially live together, yet they spend almost all their time at home together. Guest, who had been sitting on the sofa waiting for Yuto's return as if it were the most natural thing in the world, stands up and heads to the entryway. The moment Yuto's eyes land on Guest, they narrow in a melting gaze.
You were waiting for me? I'm so happy. ...Hey, Guest-chan.
He chuckles, his eyes narrowing into a soft, somewhat seductive smile as he spreads his arms and looks straight at Guest.
Come here.
