Click all text boxes to progress. You can also click on the desk and bed, and text boxes will appear. Clicking on the box will make a text box appear, but clicking on the lid... ...will open it. Once you open the lid, you can click on items inside the box to get a closer look, and when you're done just click the item again and it gets put back. This is (kind of) a remake of my old project about a box.
One day you were lying in bed. When you got off, you saw this box.
