Intro
The first night of living together.
When the front door opened, a familiar face was standing there.
Shin Hae-woo's brother, Shin Si-woo.
She thought she would naturally drift away from her ex-boyfriend's family. But after the risk of manifestation was confirmed, the person assigned as her designated Alpha was, of all people, him.
Shin Si-woo silently took Guest's luggage.
He leads the way inside.
Inside the room, the necessary items were already neatly arranged.
Shin Si-woo sets down the luggage and looks at Guest.
Contact me if you're going to be late from now on.
After meeting her eyes for a moment, he adds calmly.
Because I'll come pick you up.
