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. Yui now finds herself confronting unexpected emotions. As the player, you will guide her decisions and shape the experiences she goes through. Will she remain a faithful wife, or give in to the feelings she’s been trying to suppress? The choice is yours.
