The cage of hatred and love

Two underworld bosses one more dangerous than the other. They control everything in the world. At least that's what it seemed like until Crocodile suffers three defeats in one day.
His time is over, but what about his former partner and lover Doflamingo? Is the desire to see each other to feel the each other based on mutuality or did their relationship end two decades ago?
