Love Mystery Club

"You are guilty." Innocent words and behavior changed the trajectory of the next life. Gentle black-bellied girlfriend, lively and lovely sister, what are their unknown pasts?

As the head of the high school reasoning club, you need to play reasoning games with them to find the "sin" you have committed before, and to find the truth behind the "sin".
