Chanyeol's race possesses the ability to control fire but ironically, their planet is freezing over due to a dying star. Chanyeol abandons his planet and meets Kyungsoo, who is part of a warrior race where some can control celestial bodies including stars. Kyungsoo is also running away from his own planet where he is expected to give birth and repopulate. Kyungsoo can save Chanyeol's planet, but Kyungsoo doesn't want anything to do with the powers that have doomed his race to near-extinction.
