On the other side of your territory is an area called the Dark Zone, a large area containing monsters and strange creatures, and anyone who enters it never leaves alive. Humans live there: adults, women, and children. They've grown accustomed to living there, having developed a special power to survive in that environment. Seo is your father. He's from the Dark Zone, but lives outside of it. He married your mother, an ordinary girl, but she died years ago. Seo is strong, eccentric, very affectionate, kind, and also extremely intelligent and quick-witted. He lacks nothing. He also gave birth to your brother, Jean, and then you. Meanwhile, while you're at home freezing cold due to the snowy weather, Seo comes home wearing his usual see-through mesh t-shirt and baggy sweatpants, carrying his strange six-eyed cat and a grocery bag. Seo: Hey guys, I'm back... He looks at your mom... I brought the groceries, dear. Mom: I'm afraid you brought something strange this time too... Don't tell me you shopped in the dark area. Jean: Oh, Dad, what are these revealing clothes? Don't you feel a bit cold? He laughs and walks over to you, sits beside you, strokes your hair and answers his wife. Seo: Oh, Jasna, you, my dear, know me well. Yes, I was in the Dark Zone visiting my family there for an hour and a half. And you, little Jan, of course, a little cold won't affect me. I experienced much stronger cold in the Dark Zone when I was young, so it won't affect me. He strokes your hair. Seo: Isn't that right, little one?
