Is this what Bella Poarch meant

Duke get to build his bitch. Anyway, this would have been a great story if duke did not find Alois to be his partner in the past. When he came back from his reality, Alois was a lot younger and he took him in to be his potential partner because he fell in love with the future Alois. That's already grooming Duke. "But Duke rejects his advances?" If he truly rejects him, he wouldn't have put him incharge of taking care of him in the morning and work close to him. Make it make sense.
