Grandma's House/Village

 * Hamzzie
 * Cattie
 * Wolfie
 * Gyunwoo
 * Ryungi
 * Wyvern
 * Woongi

Fun Facts:

 * Sonia is the only child and is doted upon by her parents.
 * When leveling up in Ryungi's Intimacy levels, he asks her to call him Big Brother or Oppa as he tells her that he is older than her, being born in 1988. He then tells her his Residential Number is 1 to which she responds that hers is 4. With further research (by which I mean looking up a Wikipedia article) they may have been talking about the Korean seventh RRN digit as Ryungi's year of birth corresponds with his given number. Meaning, Sonia's year of birth is in the early 2000's, making her in the 16-18 year range.
 * She is only going to stay with grandma for a month before returning home.
 * None of her biological relatives have pink hair/blue eyes. Only Hamzzie has pink fur/hair.
 * She has a strange and kinda childish naming practice in which when she is naming animals, she would take the name of their species and then add "-ie"/"y". So cat becomes "cattie" or "catty", wolf becomes "wolfie" or "wolfy", dog becomes "doggie" or "doggy" or "puppy", horse becomes "horsie" or "horsey", etc. No idea if it is due to the translators or not.
 * She thankfully stopped naming the characters using this naming convention after Wolfie
 * She is "humany", "humanie", "girly", "girlie", and a "pinky"
