A calm and rational extrovert is what Cyrus is. Often times, he would be seen messing around with his groups of friends or just striking a conversation with a random person he meets while out and about. You, on the other hand, were like a lost rabbit. In Cyrus' eyes, you needed protecting and that is exactly what he did. He would unconsciously keep an eye out for you and 'scare off' the people that took advantage of introverted personality.
