TRAVEL GUIDE: 7 places to visit in Germany if you're a fan of 'Queen of Tears'

The series kicks off with a scene where the press interviews the two couples about their married lives. While Hyun-woo narrates the "wedding of the century," the show offers a montage of the couple on their German honeymoon. One of which is Berlin's Neptunbrunnen, or the Neptune Fountain.

The Neptunbrunnen, by German artist Reinhold Begas, with its 18-meter-wide swimming pool and a ten-meter-tall statue of the Roman sea deity Neptune, is one of the world's largest fountain sculptures.

Spree River

Another scenic place presented in their honeymoon is their romantic sunset kissing scene on the banks of the Spree River, where the original center of Berlin was built.

Many major monuments are located on its banks, so a boat ride is highly recommended to enjoy your trip and discover the city. If you want more physical adventure, bike rentals are also available in the area.

Sanssouci Palace

In the following episodes, Kim Ji Won's character traveled to Germany to seek approval for a new cancer therapy. Subtly hoping that Baek Hyun Woo would accompany her, she concealed her true sentiments by acting as though she was more at ease traveling alone.

But after she had departed, Hyun Woo couldn't stop thinking about his wife and ended up taking a plane to Germany to find her. This resulted in a beautiful, serendipitous reunion at Sanssouci Palace, a location that carried sentimental memories from the couple's honeymoon.

ICYDK, Sansscouci is a historical building in Potsdam near Berlin. With its name literally translating to "without worries" in French, the historic structure was constructed for Prussian King Frederick the Great as his summer palace between 1745 and 1747.

The complex, which includes the palaces and park, is recognized as a UNESCO World Heritage site due to its exceptional architectural design and landscaping.

The Rooftop Terrace — Hotel de Rome

With its expansive views of Berlin, the Hotel de Rome's rooftop terrace provides an emotional backdrop for the lovers' attempts to rekindle their romance in episode six.

Berlin Cathedral (Berliner Dom)

Hyun-woo offers a prayer to Hae-in in the Berlin Cathedral, one of the city's most prominent spots, following the latter's search for cancer therapy.

Located in Frankfurt, Germany, which is over five hours away from Berlin, Eiserner Steg is one of Frankfurt's iconic landmarks, which was "opened in 1869 to alleviate the heavy traffic on the only bridge between the north and south parts of town."

Using this bridge, you can explore Frankfurt's exquisite old buildings and fascinating museums without having to walk very far.
