First things first, despite the fact that this series is as formulaic as they come, it wasn't inherently awful because it was, for the most part, enjoyable. The male lead is the key justification. Both the serious and humorous portions of his performance were good, making the watch enjoyable. But how long can you hold something with just one thread?
Because there are no other compelling characters, watching each episode of the show eventually becomes tedious.

I'm going to talk about something that I've recently seen in a number of shows. when the man and woman finally start dating. The chemistry we had felt up until then fully changes into cringe. I felt uncomfortable as I saw the leads' interactions.
The awkwardness I experienced while watching the protagonists interact once they started dating is not unique to this program, but it does continuing the trend. This is very definitely caused by the lack of proper writing . I cut out a good number of shows as a result of this.(Hometown cha cha being one).
Why bother finishing the story when the sole element that was keeping you interested is no longer there?
