After Kate and Guenther shared their first kiss on Torquay's pier in the summer of 1989, their blossoming love was soon interrupted by the distance between Yorkshire and Bavaria. Two years later, they had to let go of their early romance.

In this episode, we explore rekindled loves, for better or worse, and the challenges we can face when the ghost of an old romance resurfaces.

As Matthew Syed reminisces about his own experiences, he delves into the reasons why our first loves are unforgettable.

Featuring Professor Catherine Loveday, Jeannie Thompson, and Professor Adam Fetterman.
