These are both shows that tackle the subject of nostalgia and remembrance of relationships. For "When My Love Blooms", it's more about remembering the good times of their relationship first time around in their youth, and how they can rekindle it in their later lives. While in "Go Back Couple", it's more about going back in time to their youth, and just re-experiencing their past together. In the end, these dramas cause the main couple to learn more about each other in a deeper way, and it puts them at a more mature and deeper understanding.
