Well, first you could check the official website of the production company. Sometimes they offer the side story for viewing there. Another option is to look on well - known video - on - demand services. It really depends on the distribution rights. If it's a very niche or regional production, it could be more difficult to find, but exploring local streaming platforms might also be a good idea.
Since it's a side story, it could be delving into the lives of secondary characters. It might explore how they are affected by the relationship between the liar and his lover. For example, it could show how a friend of the liar or the lover reacts to their relationship, or it could uncover some secrets about the setting or other elements related to the main story that haven't been fully explored in the main plot.
There could be characters who are on the periphery of the main relationship in the original story but become central in the side story. Maybe a rival of the liar for the lover's affection, or a mentor - like figure who tries to guide one of the main characters in a different direction. These characters would be important as they would drive the plot of the side story forward, adding new twists and turns to the narrative.
The obvious main characters would be the liar and his lover. The liar could be a charming but troubled young man, perhaps an artist who lies about his past to seem more interesting. His lover could be a kind - hearted girl, a student or a young professional, who is initially drawn to his charm. There could also be a best friend character who suspects the liar's true nature and tries to warn the lover.
I'm not entirely sure as I haven't watched it myself. But generally, it might be about the side events or the backstories of the characters from the main 'watch the liar and his lover' story.
One idea could be exploring the backstory of the liar. Maybe he had a difficult childhood that led him to be untruthful. For example, he grew up in a family where honesty was not rewarded. Another could be focusing on how the lover discovers the lies bit by bit. It could start with small things like forgotten promises and gradually lead to bigger revelations. And a third idea is to have a parallel story of another couple in the same universe, whose relationship is affected by the liar and his lover's situation.
