"Sumin, listen carefully. The fox is not your mother."
"Not mom." Kim's hypnotic words were sinking deep into Sumin's subconscious.
"Your mom is a normal human being. She doesn't have fur or a tail, and she's certainly not a anthropomorphic fox."
"Mom is human, not a fox."
"The fox is a magical creature. It appears when it wants, and does what it wants. It enjoys teasing playing with you and teasing you. It is very mischievous, and likes to disappear whenever you aren't paying attention."
"The fox is magical. It does whatever it wants to do, which usually involves playing with me and teasing me. It likes to vanish when I'm not paying attention."
Kim thought for a second. She liked the idea of a secret identity, but she worried that her daughter would miss her presence.
"Your mother is going to vanish a lot more often. She gets busy with a lot of stuff, and might leave without warning. You don't need to worry though, because she's much happier now that's she's taking those mini-vacations. She still loves you very much, and will come back when she's ready."
Sumin took a second to process this new information. "Mom is getting a lot busier, and sometimes vanishes without telling anyone. That's okay though, because those breaks are making her much happier. I know she still loves me just as much, and will come back to me when she's able to."
"Okay, now, whenever the fox says, 'Human Time', it will disappear. You won't be able to understand those words, because that phrase is magical. In addition, your mother will reappear. Remember, your mother is a normal human, not a fox. You won't question where she was, or how she came back. You will just be happy that she's back."
"When the fox says the magic words, 'Human Time', it vanishes without a trace. Instead, my human mother comes back from one of her vacations, and I'll be happy to see her."
"Whenever your mom says the words 'Fox Time', you won't hear those words. Instead, your mother will vanish, and the fox will reappear in her place. Remember, the fox is not Kim. You won't worry about where your mom went, because she's probably on one of her mini-vacations."
Again, Sumin took a moment to process this. "When Kim says the words, 'Fox Time', I won't recognize those words. I'll know she had to take a break, but I won't worry about it. Instead, I'll be distracted, because the magic fox has reappeared."
"Alright, you're going to wake up soon. When you do, your mom will be on a vacation, and you won't worry about her. Instead, you'll be confronted by a magical fox, who wants to play with you. Do you understand?"
"Waking up. Mom is gone. Not worried. Fox is here."
"That's great sweetie. Okay, wake up!" She brushed her tail against her daughter, snapping Sumin out of her trance.
