Unsurprisingly, the show has garnered much interest as fans wanted to get an inside look into the girls' lifestyles and habits. Among the nine members, one member in particular surprised viewers with her strict, carefully disciplined personal care routines.

That member was none other than Tzuyu, who takes great care to look good. When the rest of the members had gathered in the living room to natter away before heading to bed, Tzuyu quietly removed herself from the group to go to her room. 

In her interview with the production crew, Tzuyu said, "I think I'm pretty diligent." The idol was then seen applying not one but two facial masks; one which goes directly on her face and the another one on top of that to help with the absorption.  

Jungyeon mused, "[Tzuyu] really takes care of herself. Her posture is [normally] straight even when she is sleeping."
