The notion that perceiving the "true face" of love is costly highlights the struggles and trials that often accompany deep emotional connections. It encourages a deeper introspection into what it means to love someone fully, recognizing that genuine relationships may involve navigating difficult emotions and situations. In essence, Riordan's quote invites readers to consider the weight of love and the resilience needed to confront its true essence.
