Just wondering if there are any great series where the main character reincarnates and remembers his love, and somehow searches for/finds her. Sort of like Fox Spirit Matchmaker only both parties reincarnated. Big bonus if both find each other while still children (not looking for anything erotic there, just think it'd be cute to see two people with such a deep love enjoying childhood together).

Highly recommend Zense Coupling! It follows 4 couples but all are endearing in their own way.
