I wonder if this story represents the usual relationship between women and men in Korea? Do the women act so intimidatingly reserved and the men so shamelessly harassing?

We see sexual harassment in this show, forcible kisses, to assaultive touching, to sleazy requests for sexual intercourse. Rejections from women are ignored at best. Is this the way it is in Korea?

Harassing women at work, even repeatedly asking them to have sexual intercourse, would mean summary dismissal in the West.

Guys ignore that you hate them, dislike them, loathe them, don't want to be harassed, but women's opinions don't matter.
That must be exhausting for women, constantly fending off assaultive behavior in addition to work.

It may be a comedy, however it comes across as pretty weird in parts! Much of it is annoying and not funny. This includes the "candidate" scoring and haggling over FL. and other ridiculous, adolescent competitive behavior.
At least the story has lighter moments, especially in the second half, and the actors do well. Still, the ending is quite stale and disappointing.
