While Fennia is waiting with young Lucie at the day care center where she works, a handsome, well-dressed man appears. He says his name is Jegar and that he’s the child’s uncle and he’s here to pick up his niece because his brother and sister-in-law were in a car accident. Though Fennia’s not sure she can trust him, she goes with Lucie to Jegar’s penthouse, where she’s relieved to find out he’s telling the truth, but surprised when Jegar asks her to live there to help take care of Lucie until her parents get out of the hospital!
