Van, Corrin, Kaden, Seiya, and David are determined to make it in AWE Entertainment-the first company of its kind in Oʻahu, Hawaiʻi. Inspired by K-pop companies, the rigid training system is too much for most trainees to bear. But the boys promise each other they'll debut and create a special universe for them and their fans.

As the training grows tougher, filled with eerie incidents, the five members of Apple Hair ask, "Why not start now?" They begin writing the story of their universe, including the various adventures they want to set out on in their canon and music videos.

As the guys write, the universe opposes. The training gets tougher. Rivals and instructors seem to conspire against them. Old ghosts come out to haunt, and the members almost quit altogether. But what they began was a magic spark, and soon it sets fire to reality. It turns out that the Apple Hair universe has more power than originally assumed. The physical world changes bit by bit each time they create. To debut, the boys must not get lost in the fantasy that threatens to swallow them. But staying grounded is hard, and it's even harder to do so when they're tempted by mind-bending dreams.
