I'm so obsessed with Secondo using my dove as a pet name for his love because to him it represent a sort of innocent optimism, a sign of positive change in his life, reprieve from the banality and the aversion he holds for his duties in the senior clergy, freedom and relief from his own trauma and deep-rooted pain as well as a calmer state of mind and making peace with his past to move into a happier future. The first time he uses it it just feels right. And he is a romantic, he wants you to feel the implications of his use of the name, enunciating it in a way that makes the word heavy with how much emotion it carries. This man has more devotion in his little finger than others carry in their whole body. There is no way you won't feel utterly loved by him at all times.
Am I over-analyzing my own HCs? Maybe.
