I waited until night when both Tochaki-san and Tokita-san were asleep in their rooms. I sneaked downstairs and looked for some wrapping paper in the storage room and luckily, there were a lot of different selections. I chose a simple one with a Santa's face pattern with a snow man and went upstairs to wrap the presents. It took a long time since I have no idea how to wrap presents but I was able to neatly wrap the box with Tochaki-san's necklace together. The store didn't give me a box for Tokita-san's tie so I just simply wrapped the tie with the wrapping paper. It was a lot easier. Now all that's left is wait until Christmas day.
