Sterling opened his mouth in surprise as he realised it was true. He did not crave the sweet venom that flooded him every time Callum sunk his fangs into his neck. He was just too preoccupied to notice.
His occupational disease was that he was that he was quite detail-oriented. He would notice the smallest changes during his work, so he did the same in his personal life. He could not believe he had overlooked something so important.
After giving Callum the bite, he froze him out and refused to even answer his calls. He did not want to deal with the aftermath of the event, especially after learning that Callum lied for years, even after they became close friends.
Throughout the entire period, he kept replaying the interactions between him and Callum, trying to find out if he had missed something. It made him feel like he was not attentive enough because he could not find clues.
