Ellipsism (2021)

Alex and Ona have long since broken off their relationship. When everything seems to be over, Alex decides to come back into Ona's life by showing up at the home they once shared.

As he walks through each room remembering his past life, he hears the sound of the door: it is Ona, who does not know, yet, that their relationship was not broken for a simple matter.
