Talk to Sadness at the tall door, then slide the lower blue section left until its black line joins the keyhole symbol above it. This guide covers the early underwater door shown in the release playthrough, not every later Heart Palace or a relationship-locked barrier.

Finish the conversation at the door

Follow the underwater route until Lunne meets the small Sadness emotion beside a tall stone structure. Complete the conversation. Sadness then points out the door, and Lunne’s next interaction brings up its movable section.

Compare the upper keyhole with the black line on the lower blue section. This is the door covered by the steps below. Wanizame Wajira, 109:45.

Complete the keyhole symbol

  1. Interact with the indicated door section after the conversation.
  2. Select the lower blue section with the vertical black line.
  3. Use the displayed movement controls to slide it left.
  4. Align its black line with the upper keyhole so the symbol is continuous.
  5. Let the opening animation finish and continue along the route.

Move the lower section left. The goal is one continuous keyhole shape, rather than walking Lunne up against the closed door. Wanizame Wajira, 110:03.

The breaking-door animation confirms the solution. You do not need to search the surrounding area for a separate inventory key for this door. Wanizame Wajira, 110:09.

If you cannot move the section

Check that the conversation is finished and that you entered the door interaction. Ordinary character movement does not manipulate the puzzle. Use the Move, Select and Cancel prompts shown for your current input device; a different controller layout may show different buttons.

If your obstacle has different symbols or asks for relationship progress, stop comparing it with this door. The screenshots identify a specific early puzzle. They do not establish that an unrelated barrier can be opened by repeating the same movement.

Once this door is open, continue exploring the Heart Palace. The opening animation is your confirmation; there is no need to keep moving the section afterwards.
