In this case you cannot talk about error do, but definitely of a promotion with a major discount.
If you want to take advantage of this kind of offer, you have to be willing to make some compromises, in this case flying from the capital of Ukraine: Kiev.
By doing so, you can knock off a truly unbeatable fare to South Korea, via Frankfurt or Munich, aboard one of the last 747/800s still in operation or on the newest Airbus A350s in Lufthansa's fleet.
The fare for a round-trip ticket is less than €600 to fly from March to July with minimum stays of 2 nights to a maximum of one month.
Important is the amount of qualifying miles that can be earned, crediting the flight on Krisflyer, Singapore's program, will earn 125% of the miles flown, similar value for Miles & More users. Unfortunately, in this class you do not earn on other Star Alliance airlines, such as Tap and Ethiopian.
