From his initial refusal to undergo treatment, Yue Lou eventually opens up to Yu Zhi. Despite their differing values they become close friends. Meanwhile, warlord Zhan Jun Bai, tycoon Zhao Jing Ming and rogue gangster Zhou Huo continue to make trouble, even attempting to murder Yue Lou. At this time, the secrets from the past start to bubble to the surface.
