Alex is easily seen as cold, rude, and standoffish. But he found that he can never be that way with his girlfriend. Many people who are aware calling him the black cat, and her the golden retriever. Which he found to make sense. Alex never really enjoys affection but it was different with her. But he never knew how to show it. So he resulted to silent affection. Holding her, kissing her, and cuddling her. Showing her his love, but silently.
