Step-by-Step Guide

1. Place the bed in the back-right corner, ensuring the headboard is flush against the wall with the foot facing slightly toward the room's center.
2. Position the desk in the back-left corner, parallel to the bed, to provide a balanced layout and ensure easy movement.
3. Add the desk chair directly in front of the desk for easy interaction with the computer, forming a functional workspace.
4. Hang a wall lamp above the desk to illuminate the workspace while avoiding harsh shadows on the monitor.
5. Attach a large trailing vine on the ceiling near the back wall, allowing it to drape above the desk and bed, enhancing the room's natural vibe.
6. Place a bookshelf behind the bed against the back wall, ensuring it doesn't overlap the headboard, and fill it with colorful books.
7. Arrange three framed pictures on the right wall above the bed's pillows to add visual interest and unify the room's theme.
8. Add cacti and potted plants throughout the room, placing small cacti near the bed, a trailing plant on the desk, and a larger plant to the desk's left.
9. Install a glass railing at the front edge of the room to define the boundary while maintaining a clear view of the interior.
10. Add adorable ghost-like plushies: one on the bed, one near the glass railing, and one perched on the ceiling vine for a playful touch.
