Liu Zhenyu (Xuanbin), the head of the investment company, went to the ancient Spanish city of Granada and inadvertently experienced an AR game with the theme of the city's historical amorous feelings, and met the game designer's sister Zheng Hee-joo (Park Xinhui) due to the need for investment. To Liu Zhenyu's surprise, in the process of experiencing the game, the real world was closely entangled with the game world, and former friends died strangely in the game, and even turned into the game's NPC, appearing repeatedly as enemies / allies, forcing Liu Zhenyu to be in an eternal fighting state, physically and mentally exhausted. To some extent, Liu Zhenyu is broadcasting games live to TV viewers around the world, and we have become "cloud players", guessing the tasks and rules of the game at the next level while upgrading through Xuanbin's perspective.
