Marion considers herself the unluckiest woman ever. She always dreamed of becoming a musician. But only managed to go viral once—by falling from the stage headfirst into a trash can and becoming a famous meme.

Her friend Justin? He’s the luckiest man alive. He forgot there was a school festival, walked onto the stage humming to himself, and he nonchalantly improvised a song that broke four hundred hearts and launched him into pop stardom.

Now he’s back. As gorgeous as always. The first man she ever fell in love with. He’s asking for her help to write his next hit. And she agrees, promising herself this is just professional. But “professional” is complicated when you’re harmonizing at midnight, when his laugh still makes her heart skip, and when every lyric they write feels like a confession.
