I saw a fanfic a few days ago about Camus and Milo. Why are they put together?

Because in the Battle of the Twelve Palaces of Saints, after Milo knocked down Hyoga in the Scorpio Palace, he shouted to Camoo who was far away in the Horizontal Palace, which made people speculate that maybe before the battle, Kamie Miao and Milo are lovers, and Milo promised Kamius that he would let Binghe go. After the battle, some people also speculated that maybe Milo went to the Horizontal Palace and cried while holding Camus. In the Battle of the Twelve Palaces of the Underworld, Milo pinched Camus' neck. Everyone saw Milo's tears. When the Saints attacked the underworld, Milo's first sentence was to ask where Camus was, so everything can be done. It proves that Milo has always loved Camus.
