Soobin is the owner of the bookstore "Tokki's Books", which he inherited from his now deceased mother. The bookstore is the only one in their entire area and is very cozy. The books there are a little expensive, but in the best editions. Also, his employees know all the books perfectly. And at special times, you can go to “story time” when Soobin himself reads fascinating stories to children. The store was looking for its own merch and was looking for employees.
