Replying to myself but thinking of the actors, I suddenly remembered: While appending brother/sister like -ge, -jie, -mei to the end of someone's name is a very common thing to do as well, be very careful in Guardian!

Bai Yu calling Zhu Yilong "Long-ge" - A-OKAY. Guo Changcheng calling Chu Shuzhi "Chu-ge" - Awww. How cute.

Zhao Yunlan calling Shen Wei "Wei-ge" - Nooooo. That means viagra.
