Characters with IQ less than a pair of socks.

The FL is so cliche yet so important to the story that you need to bear with her if you want to finish the series. However, if you have an IQ of above 20, you will go bat-shit crazy while watching it.

The female lead acts fine, but the character itself has the IQ equal to a pair of socks. Throughout the series, it is very easy to find repetition. It is like a low budget manga plot at this point.

Female Lead does/says something she shouldn't > problem > male lead fixes it > repeat

Not recommended.
