On a weekend morning, the doorbell rang. Given how early it was, the woman sleeping sweetly had to force herself to open her eyes.0

Ding-dong. When she heard the doorbell ring once more, she rose and got out of bed. “Who is it…” The woman opened the room’s door and trudged to the entrance. While walking, several children, who were playing in the living room, rushed forward and clung to her. “Uh…hey kids…wait a minute…” The woman had a little trouble escaping the children’s hands as they grabbed her calves and dragged her back. And while she was about to head to the entrance like this—0

“Where’s Dad?”0

She heard a familiar voice.0

“He’s not home, right?”0

When the woman turned around, she saw a red-haired girl with an arrogant expression sitting in the living room. Judging by the storybook in her hands, she seemed to have been reading it for the other children. Somehow, unlike her usual grumpy expression, she seemed a little nervous. The woman tilted her head and nodded.0

“Yeah…probably? Mr. Soo-Hyun went out early in the morning, saying he had something to do today.”0

“Yeah, that’s a relief.” The girl with red hair, Suna, sighed quietly.0

The woman quickly blinked. She knew a bit about what type of existence Suna was, yet Suna just said that something was a relief; it was the first time she had heard such words from Suna.0

“But be careful, just in case.”0

Suna even gave her a mysterious warning. The woman felt a bit more awake after this and looked at the entrance instinctively. She stared at the door with sharp eyes for a long time.0
