Should Greg Have Another Boyfriend?

Hello everyone. I’ve been thinking about an idea for a while and would love to hear your opinions before deciding whether to move forward. I’ve been considering introducing a new character to Greg’s story: another boyfriend. This would lead Greg into a polyamorous relationship, where he would love both of his boyfriends equally. The idea is that this new character would be an imposing Doberman, as devoted and loyal to Greg as Connor is. But before going ahead, I’d like to know what you think. Would you like to see this polyamorous dynamic in the story? What are your thoughts on the idea? Your feedback is very important to me.
