There are four characters: Jeong-ho, Su-jin, In-ju, and Yu-jeong. They are all involved in the arts. Jeong-ho and Su-jin are lovers, but Su-jin is seeing another man without Jeong-ho’s knowledge. In-ju has a crush on Jeong-ho and wants to confess it to him. Yu-jeong also has her own story. The film calmly develops each of their stories until the middle. After the midpoint, it seeks a significant structural change. In this film, time no longer flows in order. Merely Known as Something Else is the second feature by director Jo Heeyoung, who debuted with The Continuing Land (2022). The film features characters crossing paths in the same space without knowing each other, time from today and yesterday intervening in each other’s dimensions, which makes the distinction between fact and truth ambiguous. The solid cinematography is excellent, and the virtue of the film lies in its attempt at a complex, multi-dimensional structure, which enhances the emotional resonance rather than the narrative.
