What is first reaction to seeing Romeo?

At first sight, Rosaline appears to have bewitched Romeo's soul. He idealises her and believes she is the epitome of beauty and perfection, making her unattainable and almost divine to him. However, when he meets Juliet at the Capulet ball, his perceptions shift, and he declares that Juliet's beauty surpasses even Rosaline's. In Romeo's eyes, Juliet becomes the ultimate embodiment of love and beauty.
