Tonari no Kuuderella wo Amayakashitara, Uchi no Aikagi wo Watasu Koto ni Natta

A high school student named Katagiri Natsuomi lives alone for two years until a girl named Yui moves into the next room. Yui has black hair and blue eyes and is part of the nobility. At school, she is known for her cold and distant demeanor, earning her the nickname “Cool-de-rella.” Natsuomi learns that despite her aloofness, Yui avoids depending on others not out of arrogance, but due to her own naivety. Seeing this, he chooses to assist her, marking the start of a close and intriguing connection between the two neighbors.
