A habit of yours that he loves #3Harry:
Playing with your hair when your bored but he likes it better when you play with his hair.
When you start humming/singing at random moments. He always joins along with you.
When you talk in your sleep. He finds it adorable while you're embarrassed about it.
Biting your lip especially when your nervous. He thinks it's really sexy.
When you talk to yourself. He says it's annoying but secretly loves it.
