Hulu has announced a direct reservation for the spin-off "How I Met Your Mother of Mom and Dad,"How I Met Your Father of Mom and Dad," starring Hilary Duff. The derivative drama project led by Isaac Aptaker and Elizabeth Berger has been developed by CBS since 14 years, but has failed three times in a row. In the 10-episode spin-off, Sophie (Hilary Duff) tells his son how he knows his partner, just like Ted Mosby did in the mother play. The Romance of Mom and Dad is set in 21 years. In addition to describing the heroine's love story, the protagonist and friends will also explore their own lives and work together to find love in an era dominated by dating software.
