The Duke's Hidden Baby: BOGO!

He is an absolute bigwig who is decisive, cold, and callous. However, he just can't stop tangling up with her, always eager to give her all his love. On their first encounter, he questioned:"Was that you 6 years ago?" The second time they met, he was holding a paternity test report. "You're still gonna deny he is my son?" After multiple encounters, she asked: "His Excellency the Duke, are we done?" The man broke a charming smile: "Of course not. We are expecting a second baby.”
