Zhang Ruxin had indeed contacted Lin Gantang.
Right when Gu Shuyue suddenly went abroad, Zhang Ruxin discreetly found out that Gu Shuyue's departure was not only because her playing with other's emotions affected the Gu family and even the Gu Corporation's reputation, but also stemmed from her feud with Lin Gantang.
Zhang Ruxin was close to Gu Shuyue, and she had had her conflicts and frictions with Lin Gantang as well. After Gu Shuyue was forcibly sent overseas by her family, Zhang Ruxin feared that Lin Gantang would turn around and settle accounts with her, so she tried to curry favor with Lin Gantang multiple times during that period.
It was just that Lin Gantang did not pay her any attention.
As time passed, with no move from Lin Gantang, Zhang Ruxin gradually let down her guard, believing that she wasn't going to hold a grudge, and began to make connections with Song Jinwen.
