These two dramas share the same sense of humor and both are mainly pure comedies so if you found yourself dying from laughing in Waikiki then you'll do the same for The Boy next door or vice versa. The characters are also very similar (idiotic and childish), the bromance is off the charts and while the overall plots of the two dramas are different, in essence, they are the same; idiotic characters finding themselves in idiotic situations that have you rolling on the floor.
