Natsuomi, a teenage boy residing on his own for two years, welcomes a new neighbor, Yui, into his home. Yui is a stunning young woman with raven black hair and piercing blue eyes, who goes by the nickname "Kuudere-lla" due to her aloof demeanor at school. Initially, Natsuomi perceives Yui as an independent and self-reliant individual; however, he later discovers that she is rather naive. Despite this revelation, he decides to assist her in overcoming her reliance on others. Tonight, they are excited about their shared meal of fried chicken, which was chosen because it was inexpensive. This marks the beginning of a delightful and tantalizing relationship between the two neighbors.
