Chi Yongzuo, the president of Chi Group, and Chi Yusheng, his designer brother, reunited because of the polar scientific research station project. The two went from a business game to fighting the enemy side by side, uncovering past misunderstandings and confirming taboo feelings. They join forces to seek revenge, resolve the family crisis, and finally break down the barriers, turning their bond into the never-ending sun in the Arctic Circle to stay together for the rest of their lives.
Purpose: Using the polar day of the Arctic Circle as the core metaphor, explore the dialectical relationship between fetters and freedom, possession and compromise. In the entanglement of business games and family grievances, brothers Chi Yongzui and Chi Yusheng broke through the shackles of the world and inner barriers, proving that true love is each other's shackles and salvation - like the light that shines day and night, love can dissolve all shadows and become a never-ending companionship.
