Mafia Daddy, Pay Up!

After his mother dies, three-year-old Liam arrives at Ethan Blake's door with an IOU for three years of child support. His existence breaks the Blake family's succession rule, so his uncle Victor and aunt Diana try to drive him away and frame his mother as a runaway thief. Ethan protects his son, uncovers the recording, deleted pleas, missing money, and forged letter, and gives Liam and Noah a real home.
