Since it was nothing more than a dream, he had to eventually wake up from it no matter the amount of pain that it costed them both.
Therefore, he had returned to his role as a guardian angel. He would appear whenever she needed him, and she would never know he was there for her. Just like tonight, he had been worried when she ventured into the nightclub. He had followed her but didn't show himself.
Even though the music was booming and the crowd was noisy, all he heard was the sound of her crying.
He knew his appearance would lead to many complications, but he couldn't help himself.
In the haze of her alcohol-addled mind, she thought he was a part of her dream. When she leaned into her, the rational part of his mind told him to lean away, but his heart made him reach out to hug her instead. He allowed himself to materialize in her 'dream'. it was not until Qin Yinan showed himself that he disappeared back into her shadows.
