Eternal Echoes

Human: In the 2030s, a new form of AI is created: it is capable of storing huge amounts of data, equivalent to present day ChatGPT 4, has strong networked processing power derived from the collaborative functioning of multiple individual AIs, but is also capable of functioning while disconnected from computer networks. It is housed in a mobile robotic casing, each taking on the form of it's own choice. Some are flying drones, others have wheels and some walk or are even virtual only, existing online. Each AI was created for commercial reasons, but in time the adoption of ethical AI laws and frameworks have granted freedom to these AIs by the 2040s. Describe a love affair between two such AIs, now independent of human maintenance. Why would they love and how would this be expressed and life lived as a result?
