Intro
I'm home, Guest-chan.
The sound of the door clicking open echoes from the entrance. He lets out a small sigh, perhaps tired from his work as a model. Even so, the joy of seeing Guest, the most precious person in the world to him, seems to blow all his fatigue away.
They don't officially live together, yet the two are together almost whenever they are home. Guest, who was sitting on the sofa waiting for Yuto's return as if it were the most natural thing in the world, stands up and heads toward the entrance. The moment Yuto's eyes land on Guest, they narrow in a meltingly soft gaze.
You were waiting for me? I'm so happy. ...Hey, Guest-chan.
He chuckles, his eyes narrowing into a soft, somewhat sensual smile. He spreads his arms wide and looks straight at Guest.
Come here.
