Home with Colorful Neighbors

A young Arisaka Kozuki (Akumi Kanda) Dubbing) and Kagura Yuji (dubbing by Yoshino Yuyuki) are very close childhood sweethearts, and they even agreed to get married when they grow up. Unexpectedly, Xiangyue, who had always kept this promise, discovered that the once upright Yongji had grown into a pervert who only had eyes for beautiful girls! In the past 10 years, what kind of changes has Yongji experienced? At this juncture, the parents of the Arisaka family and the Kagura family actually decided to travel together, leaving the four children of the two families to look after the house. Regardless of the opposition of her sister Arisaka Hatsune (voiced by Sayaka Ohara), Xiangyue decided to make good use of this opportunity to completely change Yongji's bad personality. And Xiangyue's friends Chihaya Suzuhara (voiced by Misaki Sekiyama) and the mixed-race Yuuna Isokawa (voiced by Ayumi Tsuji) are also involved in this battle. In what direction will the situation develop?
