The writer & director failed epically with the female lead (FL) character. The FL is so annoying, immature, childish, etc. Excessively Aegyo... Her babyish, cutesy voice made me cringe. She freaking cries & hides like a child because she didn't get invited to eat with people that she already knows didn't want to be around her. She skips & twirls around like a child.
I also noticed when an attractive male appeared in the series, adult women are staring, giggling, whispering & taking pictures of the male. Why portray adult women as being so shallow?
Yes, the series is for entertainment, but you can still achieve that without unrealistic & excessive behavior.
