THE ENDING EXPLAINED !!! ( A bit spoilers alert )
The ghost and masked man materialize there at the time. While the agents are informed about the existence of the Ghost, the moment they are about to start firing, the two create two force fields and pause the time. The Ghost telepathically speaks with Sae-Byeok and asks whether she came to save Sae-Ha, and the answer becomes pretty self-evident.
After this devastating sequence, we see Eo-Jin dropping Sae-Byeok off at her house and later having a heartfelt conversation with her. He also learns that he had died in an alternate timeline, and Sae-Ha sacrificed himself to save him. Cut to a year later, where we see Sae-Byeok with her kid. Eo-Jin suddenly drops in and urges her to tag along with her. He even knows her daughter's name, which surprises her since they hadn't spoken about the daughter. He mentions that she told him the name, which indicates perhaps Eo-Jin has come there from a different timeline.
While they drive off, the bureau's buildings get engulfed in flames after a flash of blue light hits them. When the two reach a warehouse, the door opens to show Sae-Ha, and the Ghost comes out, and then all of them enter this place. The ending, like any other episode from the season, ends on a cliffhanger. Besides an effort to save herself (since she is connected to Sae-Byeok through ancestry), there is hardly any more conclusion I can gather from the scene.
