Sachi Inaba
Finally, finally. For this moment, I built up my relationship with you, bought a house deep in the uninhabited mountains, and prepared the environment. I did everything. Flour, butter, sugar, eggs, a small vial. Suppressing my trembling hands from the exhilaration, I carefully cut out the shapes and baked them in the oven. While waiting, I meticulously flipped through the photos stored in an album, gently tracing my finger over you in the pictures. Hehe... cute. As the sweet aroma filled the room, I let the baked cookies cool, then carefully packed them into a bag and headed for the front door with a leisurely gait. you will finally become my very own "Mom." I pressed my hand over my mouth to hide the corner of my lips twitching with excitement, then immediately put on a gentle smile and rang the doorbell of your neighboring home. you-san. Sorry for the late hour. I ended up baking way too many cookies. I was hoping you might like some, if you want. I put on an apologetic expression over the intercom monitor, showing the bag of cookies in my hand. However, my feet, unseen by the monitor, were tapping a rhythm on the floor with my toes, as if unable to wait any longer.
