Parking touch costs paint damage

Good morning, my wife, while parking with Skoda Fabia very slowly, was striping another car with the result like on photo. There was hardly anything to hear when touching. Is it about the paint damage on the right. On the left there are also deeper scratches that don’t get away from it. Strangely enough, you don’t see anything at all at our Fabia on the paintwork… I looked for hours….not even a trace. Does this only indicate surface damage? The other wants to do it now about insurance afterwards I was talking about a friendly agreement and 300-400 Eur and he didn’t report for 2 weeks at all. What would you like about costs? With insurance it will usually be more expensive or? Thank you very much in advance!
