M. M. Doesn't like herself, it can be said that she doesn't like him very much - this knowledge has been deeply remembered by Cullom ten years after arriving there: he gave her a slap in the face when they first met (although he also helped him show the way), and when she was about to go back, she also said that Mr. Mute just wanted to use Cullom (although Cullom didn't believe it at all). So, to be honest, Cullom Skull didn't want to see M. M. At all, whether it was ten years ago or ten years later.
But you must know that there is a saying in this world that enemies never get together.
