Both consist of four different stories with different characters that arent actually connected but all have one thing in common (in Persona the main characters are all portrayed by IU and in The Table all the stories happen at the same cafe/same table). Also the person who directed and screenwrote The Table also directed and screenwrote one of the stories in Persona.
The Table (2017)
Similars
Both movies are about people having conversations in cafes (and other places too in shades of the heart) with a less than 80 minute runtime. Theyre slow but calming and rely on telling rather than showing plus theres multiple mains whos stories are connected because of one thing (in the table its the table and in shades of the heart its the main character). They also have the same director and the poster is similar too.
Both are films with multiple stories focused on human interaction and conversation. Both are a little slower. They have the same director and screenwiter too.
Both tell separate stories of four women unrelated to each other. While The Table (2016) is a film wherein all we see of these women are the conversations they have on the titular table, in Love Scene Number (2021) we get more backstory and time (two episodes) for each woman's story. Thematically they are alike because they show us these flawed women who are at a point in their lives where they have to decide on something that could affect their lives moving forward. This theme is more on the nose in Love Scene Number, and The Table does it ever so subtly but will still hit hard.
