Was FL brought to the company to give second chance to random employees? I can't understand what she is doing.And why should ML have to suffer. Is she trying to catch a criminal? Why can't she just tell the ML what her plan is..? Why is she trying to create strife in the company...Also her behaviour towards the ML is not justifyable even if it is a part of her plan.And what is the use of ML trying a bra? does he have breasts? can he really evaluate them?If their company sells condoms, what are saleswomen supposed to do? script should have some logic.

MC is a self-righteous jerk

MC believes Na Do Hee is not a person but some doll that the Gong brothers possess. If his younger brother wants it, he can just give it to him.
