I think it is not dangerous. It is important to choose a country from Europe far from Russia. I recommend going to Spain. I think it is a perfect country for someone who has never been to Europe. It is always warm there; you can go to any part of the year and feel the warm equatorial wind. Also, there are a lot of apartments for travelers for rent. You can find a comprehensive list of them on https://spanelskonadosah.cz . I like it because you can choose depending on the price you would like to spend, and the prices are directly from the apartment owners.
I think that by August all covid restrictions will be removed from all European countries, so I think that traveling to Europe is a great pastime for a young couple, you will never forget it. I'm also flying to visit my brother in Lisbon at the end of August. I think it will be a great trip, especially since I found the website (click here ) where you can find free tours of European cities. I think I will fly to Paris after Lisbon, then to Vienna and see these beautiful cities again. I hope my post will help you, and if there are any more questions, then PM me.
Considering today's unstable situation in the world, travel planning is a bit scary. But, for example, I have a honeymoon this summer. I studied this site https://tripbirdie.com/honeymoon-in-st-croix/ for a long time and all the information about flights and still took the risk of booking a hotel on the island of St. Croix. I hope everything goes well.
