Maschenny is a psychopath as nearly all Zahard princesses except maybe Garam and Yuri, but Adori must be the head of psychopaths, because even for Maschenny she is on another level. And based of my interpretation of manhwa, basically 99% of them are obsessed with power and influence, and wouldn't settle down with anyone less than Zahard, maybe Enryu or Phanta, because in their mind it will be below them to do with anyone else. The only exception must and will be Baam, because any good story must rhyme, for TOG's part the main rhyme is Arlen/Zahard unrequited love, that started all this shit to begin with. So in some perverted ways Baam ending with one of Zahard princesses is Zahard only dream came true, aka part of himself ended up with part of Arlen.
