The quote from Katie McGarry's book "Dare You To" reflects a deep emotional commitment. The speaker is expressing that what they offer to another person is not merely a fleeting memory but an authentic piece of their own heart and soul. This emphasizes the intensity of their feelings and the significance of the connection they share.

In this context, the act of sharing one's heart suggests vulnerability and trust. It illustrates the idea that true love goes beyond surface-level experiences; rather, it involves giving a part of oneself to another, fostering a profound bond that can last a lifetime.
