I guess Subin learned it properly after appearing on TV.

When Sanghyun was talking about INFP plotting, he said to dress nicely and be cute next to him.

It was so funny how Subin's expression suddenly changed into concentration mode.

Soobin thought that was a bit weak, but she personally taught me her own plotting method.

Now, if Bonhee comes out wearing pretty clothes, I will definitely be conscious of it.

This isn't just an analysis, it's almost like I've gained some insight.

Subin is naturally good at observing, and this episode was one where that observational ability really shined.
It was also very accurate to interpret that Sang-Hyeon had planted a small device in Bon-Hee's head.
