Ovi aukeaa is Finnish for the door opens, and the clip does exactly what the label promises: a brief, clean recording of a door being opened. It comes from a user generated soundboard library rather than a film or game, which is why no character or production is attached to it. Short everyday effects like this stay popular because creators need scene transitions that feel real, and a two second door opening fits anywhere a scene changes. It pairs naturally with a door knocking sound effect, turning a knock at the door into a full entrance in a single edit.
