These sketches are for the hairpin shop, or gift shop.
There are plan for the shop and shop designs.
The next ones are sketches of concept art for the scene when Sombat gives Arunya a hairpin. The top left one is an angle of Arunya looks at Sombat. We see both actions of the characters. The bottom one is another angle which I think it might look more romantic with soft lights of lamps from the lamp shop opposite the hairpin shop.
Also, the sketch of Arunya when she was alive.
