>>56149212The only reason why Cyrus doesn't have a partner is because he's a depressed nihilist who doesn't value emotions and thinks they're a flaw of humanity.
If someone tried to flirt with him, he'd turn her/him down instantly because he's not interested.
He's even canonically stated to have charisma and be very good with words, which is why Team Galactic adores him and he pulled three hot admins to work for him. But he doesn't care about anything other than his goal and he's too absorbed in his negative view of emotions to perceive others as anything more than either obstacles or tools to carry out his plans.
Cyllene is just a serious and strong-willed woman who isn't conventionally attractive, she has none of Cyrus' bs infecting her mind.
