Maybe it's my rotten toxic BL brain talking BUT I really find Romeo attractive. Honestly, if the author decides to give him a proper redemption, I would totally support it. THIS MO*HER F**KER IS HOT AF, has a very questionable but vey unscrupulous/wild personality and it seems that he truly feel some kind of love for his wife and son (or maybe is just a obsession). I love a good story of a villain turning into the ML. Romeo (for me) is way more interesting than the actual ML. Because he seems very flirty and decided.
What if she (Juliet) tries to take the child of Rosie? Technically the father have the right to do so, and Juliet may say that their home is more stable since Rosie is still single.
