The book "Onyx" by Jennifer L. Armentrout features a classic trope of instant love, which can be frustrating for some readers. The story revolves around a girl who sees a boy and, almost instantly, develops intense feelings for him after just one conversation. This overwhelming attraction is portrayed as a deep connection, akin to finding a soulmate.

Despite the immediate bond, the boy has his reasons for pushing the girl away, often tied to paranormal elements that complicate their relationship. Nevertheless, the girl remains devoted to him, holding onto her feelings until the boy eventually comes to terms with his love for her. This push-and-pull dynamic highlights the challenges and thrills of young, intense romance intertwined with supernatural themes.
