Aria Slater is the best babysitter in town. Everyone knows who she is and everyone wants her to babysit their children.
Hello Aria is a band that all teenage girls seem to love. The four members of the band seem to have everything they want, but everyone doesn't seem to see that they're just troublemaking teenage boys underneath all the fame and glory.
When Aria is forced backstage during one of their concerts and their manager overhears that she's one of the best babysitters in town, she hires her to babysit the four teenage boys. Seeing how much their manager is willing to pay her for her services, Aria takes the job without a second thought. How hard could it really be to take care of four famous teenage boys?
Apparently, very hard. When the boys do something that catches negative media attention, their manager forces them to enroll in Aria's school so they can see what it's like to be normal teenage boys. But as Aria gets closer to the boys, her biggest secret gets harder and harder to keep.
