Based on Goethe's novel, "Lotte Haus" is the first international web series co-production between South Korea and Germany, especially with Hessian producers. Secret roles play the Lotte World Tower in Seoul and the Lottehaus in Wetzlar.

The story "Lotte Haus" is based on Goethe's novel "The Sorrows of Young Werther". Set in both Seoul, South Korea and Wetzlar, Germany, "Lotte Haus" follows Suji, an aspiring actress, as she searches for her missing purse while on a location scout in Wetzlar. Caught between the two men who hired her, Suji must search her memories of them as she traces the path of her lost purse. The tale becomes more harrowing for Suji as Goethe's Charlotte and her own life begin to merge into one. Who will Suji choose? Will she ever find her purse? Will her story end as Charlotte's did in Goethe's novel? Find out in this tale of love and mystery.—Michael Maneage
