dude literally was cucking this Nazi guy, and the Nazi himself tolerated it because Sorge was such a charmer & good source of info on Japan... all the while Sorge was fooling everyone and this info between Japan & Nazis was going directly to the Soviets lmfao. Sorge supposedly even predicted the date of Barbarossa invasion but was ignored for reasons that have to do with Sorge's personal involvement with Trotskyists

"That Sorge was fluent in Japanese further enhanced his status as a Japanologist...[27] Meanwhile, Sorge befriended General Eugen Ott, the German military attaché to Japan and seduced his wife, Helma Ott... Ott now aware that Sorge was sleeping with his wife, let his friend Sorge have "free run of the embassy night and day", as one German diplomat later recalled.[33] Ott tolerated Sorge's affair with his wife on the grounds that Sorge was such a charismatic man that women always fell in love with him and so it was only natural that Sorge would sleep with his wife.[34] Ott liked to call Sorge Richard der Unwiderstehliche ("Richard the Irresistible"), as his charm made him very attractive to women."
