Koiimo Sweet ☆ Days

Yamato, a typical guy raised by his older sister and two younger sisters, deeply cherishes his siblings. When selected as part of a coeducation pilot program at an all-girls boarding school, he must assist the chairman's daughter Yurika with school duties. To his surprise, his younger sisters Aoi and Akane—separated from him for years—are already there, along with his childhood friend Ena who feels like family. Reunited at last, his sisters shower him with years of pent-up affection, setting the stage for unforgettable school days filled with warmth and connection.
