What is the relationship between Jon Snow and Daenerys Targaryen?

Jon Snow and Daenerys Targaryen are two of the most popular characters from the HBO television series Game of Thrones. Jon Snow is the bastard son of Ned Stark, while Daenerys Targaryen is the last surviving member of the Targaryen dynasty. Their relationship is complex and evolves throughout the series, eventually leading to a romantic relationship and eventual conflict.

Initially, Jon and Daenerys meet as allies fighting against the Night King and his army of undead. Over time, they grow closer, and it is revealed that Jon is actually the son of Daenerys' older brother, making him a Targaryen as well. This creates tension between them, as both have a claim to the Iron Throne and want to rule the Seven Kingdoms.

Their romantic relationship develops despite their shared bloodline, but it is ultimately doomed. Daenerys becomes increasingly ruthless and power-hungry, while Jon remains loyal to his principles and the people he leads. This leads to a conflict between them, with Jon ultimately killing Daenerys to prevent her from continuing her reign of terror.
