I'm not talking about the story concept, but the background of these two series is similar. The similarity between the two is about the relationship between a customer and a waiter in a restaurant. Apart from that, the main characters of these two series are actually *spoiler alert: childhood friends, one of whom doesn't realize it. #pp
