I'm just the messenger and I'm not claiming it's fair, but this is standard procedure everywhere in the world: when you buy a round-trip ticket (single PNR), if you are a no-show for any leg then you're forfeiting the whole ticket. If the ticket for example includes a train ride to the airport, and you don't show up for the train ride, you're forfeiting the flight as well.
Some airlines might not enforce that if you're deemed an important enough customer for them, but I just want to bring this up because being a no-show in the outbound flight and keeping the return flight is not a right that customers have in general, basically in any IATA airline. It's not really Lufthansa specific, those are rules that the whole industry applies.
