Oh absolutely! I feel like due to his past of having things taken from him and not being able to have comfort in belongings, a steady home, or even a steady safe family setting, he’s naturally very clingy and greedy with his belongings and things he grows an attachment to. Caelus included.

Even before they might be a couple, he’s subtly watching him interact with other and steers him away from them by ‘popping in’ and convincing him to go on a date with him. When they’re officially together it’s even more so often done. He doesn’t go anywhere with him without an arm around his waist. Everyone should know he’s his and envy him for having him, but that doesn’t mean they can get too chatty!
