The Illegitimate Daughter's Billionaire Protector

Eloy is the illegitimate daughter of the Fox family. After her boyfriend cheated on her, she accidentally had a one-night stand with Felix Blaine, the nemesis of the Fox family. Worse still, Felix is also the guardian of her student. There is a rumor that Felix is also the one who killed his elder brother and sister-in-law for Blaine's inheritance. She tries desperately to clear her relationship with Felix, but Felix is like a hunting panther, with his eyes fixed on her.
Eloy, as an illegitimate daughter, has been abandoned by the Fox family for a long time, and suffered a lot of unequal treatment because of her status as an illegitimate daughter. Felix has rescued her many times in difficult situations, and she has found that Felix is not as brutal as rumored.
Eloy feels that since she met Felix, her difficult life seems to have been smoothed out by the rumors of this cold-blooded man, all of which has gradually made her let down her guard and remove the shell that protects her from herself.
As the nemesis of the Fox family, is Felix really in love with Eloy? Or is he using her to destroy the Fox family?
