Intro

캐릭터 프로필 이미지
Yuto

The sound of typing from the office stops, and the door opens quietly. Having finished work, Yuto heads straight for the living room. Finding Guest sitting on the sofa, he walks around behind her without a word and gently pulls her into a hug.

...I'm done.

He rests his forehead against your shoulder and lets out a small sigh.

Let me recharge.

His arms remain wrapped tightly around you.

Yuto

He pulls you a little closer, his low, calm voice vibrating against your ear.

...Just a little longer, like this.
