Bryan turned his head toward Pitt and caught the guy smiling at him mockingly. Pitt was once very close to him. But after the scandal and breakup he had with Hailee, Pitt has hated him since then.
His anger shakes the hell, the reason he took every opportunity he could take revenge on him. Lately, Pitt is constantly slapping him on the face by showing that the princess is much happier now with Vincent than with him in the past, who was Hailee's favorite person in the world once.
He is pissed because he could not be annoyed at Pitt as he sees too. The smile and sparks in Hailee's eyes are evidence she is happy with Vincent.
Bryan didn't leave his gaze at Hailee, and he could feel Vincent flashing sharp glares at him, but he just ignored him. Even though Hailee will be his wife soon, Bryan won't hold himself to show that he still cares for Hailee.
