Real war is not weapons, but people. This is a representation of the feeling of a war raging with cunning, resentment and betrayal. War of Y is divided into four stories about struggles within the entertainment industry. Story 1- New Ship Before the ship, it wasn't easy. But this new era is even harder. Story 2 - War of Managers The story of a shipped couple who are privately a real couple. Managers and drama clash until the couple is forced to separate. Story 3 - Y-Idol A reality search for new actors—who can sing, dance, and act—and the chaos of the Idol Camp. Story 4 - Wife When one half of a shipped couple has a wife, will their future in this industry be ruined?
