After Traveling to a Beautiful Girl Game, I Actually Had to Play Cards

Bai Kong, who was born to be a fan of galgames, was accidentally crushed to death one day by the special collector's edition of the beautiful girl game that he bought in an iron box with figures that was placed high up. Such a bizarre way of death made even God laugh. God saw that he was pitiful and allowed him to travel as the protagonist into the world of a beautiful girl game that killed him. He originally thought that he would live a relaxed and comfortable harem life, but he didn't expect that in order to increase his favorability here, he would have to play a Yu-Gi-Oh style card game.
