Juno and Dawn flirted a lot, but never actually had the guts to move into an actual relationship. The two cats stayed in Cupid's garden, after Dawn had made a portal to Mania's underground temple, for Cupid and his attack force (Am'ar, Chen and Leila). This group's purpose was to rescue Psyche who had been kidnapped by the maniacs.
They actually succeeded in doing so and get away safely, but at the cost of Valentino's life. Leila teleported them back to the Valentine Forest, where they met up with Dawn and Juno. However, in the meantime Mania had taken control over Cupid's city and his people - which doesn't matter now, but it will in next year's Valentine Wars.
Anyways, from there, Cupid and Spyche moved to an exile, where they will hide until 2015, while Am'ar, Chen, Leila, Rheiko, Dawn and Juno walked out of the Valentine Forest and stayed at Gyro's Bar. And here we are, as far as I know
Anyways, just ask away if you have any more questions. I always love to help out whenever I can
