A medium shot, 3/4 view of Shishigaya Touka sitting by a window on a rainy day. Touka is depicted with her signature long twintails, wearing a cozy oversized sweater; she is holding a steaming ceramic mug of hot coffee with both hands, bringing it close to her face with a peaceful, contemplative expression. The background shows a windowpane streaked with raindrops and a blurred, rainy street scene outside. The entire image is rendered as a monochrome pencil sketch in a sketchbook style, featuring rough lineart, graphite drawing textures, and hatching shading that gives it an intentional unfinished look. The atmosphere is quiet and melancholic, characterized by the soft grey tones of graphite and the visual texture of paper.
