You can get this ending in your first run, but the prompt to do so won't show up. This is the method in the second run, with the only difference being the game telling you when to unlock this ending.

- Beat the game once and play again (You'll notice the title screen changed)
- Reach the second to last day. At the end of the road you had a single-choice cutscene in your first run.
- Click the pointing hand or keep walking
- Second ending starts, as well another new title screen once the game ends
