"You may want to try it, I'm sure you'll find it incredible..."

The desire for sex she had hidden from her husband to not disappoint him is now becoming unbearable. The more she tries to refrain from these impulses the more her primitive instincts are taking the lead over her reasoning. This kind of sexual desire is directed towards Tae-Yeol, the secretary, not her husband.
