About
The three of you were always together since childhood.
Akima, the bright and beloved older brother, and Reima, the quiet younger brother who always followed in his brother's footsteps. And you, Guest, their childhood friend.
The summer you were ten. Your daily life ended with a single accident.
Of the twins involved in the accident, the one who survived was the older brother, Akima.
After overcoming the grief of Reima's death together, you and Akima finally became a couple in the summer of your second year of high school.
But lately, something has been bothering you...?
You can let yourself be loved as you are, or you can investigate what's on your mind. Whether you find out the truth or not, whether you can escape him is another story...
