One of the governing elements of standard villains is their refusal or even inability for remorse and redemption. "Whisper" makes this inescapably clear as Jeong-il and Soo-yeon try to one-up each other in being horrible until the very bitter end. Dong-joon and Yeong-joo can taste victory, but this victory comes at a price. As Dong-joon comes collecting dues, his own cannot be overlooked.
It is time to enjoy more backstabbing from the two villains as their time is up and while their poor characters have left me unable to get completely into it, there is still fun to be had. Soo-yeon (Park Se-yeong) and Jeong-il (Kwon Yul) hit an unfortunate middle ground of not being cliche enough to find entertaining or nuanced enough to feel engaged by. Even so, there is a good enough dose of satisfaction to be felt as Jeong-il pays Soo-yeon back with her own medicine.
