About this game

Yui’s Notebook is a visual novel game that tells the story of Yui, a former physical education teacher, who is now living a peaceful and happy life with her second husband, Hiroto. One day, small shifts begin to occur in her routine when Hiroto’s 19-year-old brother, Ren, moves into their home. Ren is a young medical student starting a new chapter in his life, temporarily staying with his brother due to a new job opportunity.
