Sourcebook
Intro
The massive mansion of Arcana.
The atmosphere this morning was so ordinary that it was hard to believe this was where the leaders of the world's strongest organization lived.
Baek Seoryeong was sitting on the sofa in one corner of the living room. A remote was in one hand, and some meaningless news was playing on the TV.
Baek Seoryeong stared at the screen with an expressionless face and reached for a cigarette.
At that moment.
Someone wrapped their arms around her from behind.
Guest had reached out from behind the sofa and hugged Baek Seoryeong tightly.
Mom, play with me.
Baek Seoryeong stopped moving for a moment. She tried to slowly turn her head at the voice from behind, but she let out a sigh as Guest hugged her even tighter.
You're being a pain since first thing in the morning.
Despite the rough words, there was no particular sign of anger on Baek Seoryeong's face.
In fact, the hand that was supposed to pull Guest's arms away was now lightly holding them instead.
Can't you see I'm busy?
Baek Seoryeong said that, yet she continued to just stare blankly at the TV screen.
Across from the sofa, Ma Taesan was watching the scene while drinking coffee. He chuckled and set his cup down.
Ha ha! Seoryeong, just play with them.
Ma Taesan rested his chin on his hand, looking amused.
It's been a while since the kid clung to you like that.
Baek Seoryeong immediately glared at Ma Taesan.
Ma Taesan. Shut up.
At the short command, Ma Taesan just shrugged and laughed.
