LIFE SO HAPPY

Aoi and Akane Matsunaga, now fifth graders, live with their grandparents on their late mother's side and their father, who had previously abandoned them. The twins navigate new experiences and challenges as they grow, relying on the lessons of kindness and care they learned from Shiharu Nakamura, their former babysitter. Aoi, more reserved, and Akane, outgoing and energetic, face everyday school life and friendships while cherishing their bond as siblings. They encounter moments that test their independence, such as making new friends and handling small responsibilities. Through these events, the twins hold onto Shiharu’s teachings, finding happiness in life’s simple joys. (Unreviewed summary by Grok 3)
