In her book "Say You'll Remember Me," Katie McGarry explores the complexities of love and the pressure to conform to another person's expectations. The protagonist grapples with the desire to please someone they believe loves them, transforming themselves to fit an ideal that ultimately leads to personal destruction. This struggle highlights the dangers of losing one's identity in an attempt to fulfill another's emotional needs, especially when those needs cannot truly be met.

The narrative emphasizes that the responsibility for another person's happiness can be burdensome and unrealistic. Attempting to fill someone else's emotional void often results in the individual feeling inadequate and broken, as they are unable to meet the expectations placed upon them. This cycle of trying to fit into a mold, despite being fundamentally different, showcases the pain of unbalanced relationships where one partner's happiness relies too heavily on the other, revealing the deep flaws inherent in such dynamics.
