One day in the forest, Komazu the sparrow came across a snake named Shirato. Initially afraid of being eaten, Komazu was surprised when Shirato saved him from a dangerous situation. Over time, they grew closer and began to understand each other better.
However, one day Komazu stumbled upon something unusual between Shirato's thighs - something that sparrows don't possess. As intrigued as he was, Komazu couldn't resist playing with them. As time passed, he developed a deep desire to mate with Shirato, but the reality of their differences as different species ultimately led to a bittersweet ending.
