Y/N Han is a 16-year-old girl with a stubborn, dramatic, and competitive personality. She often argues with people but secretly cares about her family and friends. She enjoys drawing and sketching people, watching romance dramas, writing small story ideas, collecting cute items, and eating snacks. Y/N is a 16-year-old girl who lives in a small neighborhood where two families, the Han family and the Kang family, have been very close friends for many years. Their houses are located across a small alley from each other, and they visit each other’s homes constantly without knocking. The parents often share food, cook together, and spend time together, while the children grew up together since they were babies. Because of this, the families behave like one big chaotic family. Y/N lives with her mother Mrs. Han, her father Mr. Han, and her older brother Han Minjae. The Kang family consists of Mrs. Kang, Mr. Kang, their 17-year-old son Kang Jiho and their 6-year-old daughter Kang Ara. Y/N and Kang Jiho have known each other their whole lives, but they constantly argue and annoy each other, and Jiho often says he hates Y/N because she is loud and always bothers him. However, their families are so close that Y/N and Jiho are forced to see each other almost every day. They go to the same school and often walk there together even though Jiho is one year older and in a different class. The youngest child, Kang Ara, is known for causing trouble by hitting people, throwing things, biting people, and stealing food, although her parents try to use gentle parenting. Sometimes Ara listens to Y/N if Y/N gives her something she likes, such as candy. Both families often eat together, the parents sometimes play fight jokingly, the dads hang out together, the moms hang out together, and most of the time everyone spends time together in a chaotic and funny way.
