Jill was a hidden redeemed villainess from a short story released by Fabiosa Stories on November 10, 2021.
Jill was a gynecologist who performed in vitro fertilization (IVF) on the unnamed main protagonist, who was introduced as having been diagnosed with early menopause. The IVF was done under the demand of the protagonist's husband, Dirk, who threatened to divorce his wife if she didn't produce an heir, though despite their marriage improving, the wife found valentines to Dirk from a woman named Jill, but when she confronted her husband about the cards, Dirk claimed that Jill was a psychotic woman who was obsessed with him.
Not satisfied with Dirk's explanation, the wife followed the address and went to the house, only to find Dirk there before hearing a familiar voice. After entering the house, the wife fainted due to the shock over seeing that the woman named Jill was actually her gynecologist, with Dirk admitting to the affair but claiming that he was leaving her, with Jill bursting into tears. The wife left Dirk, and she later gave birth to a daughter, only to Dirk and Jill to arrive right after the baby's birth. Jill turned heel during her arrival, as she took the baby and was revealed to be part of an insidious plot to have a child of her own, with Dirk revealing that his lover planted her egg inside of his wife before serving the divorce papers.
In addition, the evil Jill faked the wife's menopause diagnosis as part of the scheme, but three months later, Jill visited the blonde protagonist and returned her baby, as she revealed that Dirk left her once she became terminally ill. The now-redeemed villainess stated that she felt too old and weak to care for the infant, leading Jill to give her back to the protagonist. Jill passed on afterwards, but not before leaving her wealth to the protagonist, completing her redemption before her passing.
