What's the Name of That Book??? discussion

This romance is about 2 older teens (maybe 18ish?). H is in a band with his brothers and his parents are his managers. They are currently on a bus driving around ready to go on tour. He meets h and they fall for each other. I think h has a hard home life. They plan to go to her prom together, however H's brother sends h a message telling her to leave him alone etc. she gets upset and he gets forced to leave for the tour. During the tour he finds out what his brother did. He then sends out a global message for the girl of his dreams, they just have to answer a question. She then answers the question right and gets to go to his show where they finally re unite.
Read in the last couple of years. Very young adult, don't believe it was very explicit.

Rock and a Hard Place by Angie Stanton maybe?

Yes that's it, thank you
