They both involve time travel. While JFL is only for a moment back in time and TPR they travel back 20 years. Both involve the couple traveling back together. Both show a couple that had misgivings and who did not get along but later on they create a strong bond.
Both involve schemes in the court that can only be stopped because of the time travel to give the couple the edge.
