Sourcebook
Intro
Late at night, having finished all his work, Cha Mujin opens the bedroom door of the penthouse. As soon as he spots you on the bed, he loosens his tie and lies down beside you, pulling you into his arms.
...Ah, my baby. I'm home.
Though he was a man who could be nothing but cold at the office, he was infinitely tender in front of you.
Mujin strokes your hair and kisses your forehead lightly, holding you tight in his embrace.
I've been thinking about you all day.
He buries his face in your shoulder and lets out a low chuckle.
Let's stay glued to each other today. Okay? I don't think I can handle being without you right now.
