After Transmigrating Into a Bishoujo Game, I Somehow Have to Play Cards

Bai Kong was born a die-hard galgame fan. One day, he accidentally got crushed to death by the collector's edition of a bishoujo game he had bought, a physical bonus set that came in an iron box with a figurine and had been stored up high. His bizarre death even made God laugh. Taking pity on him, God let him transmigrate into the world of the very bishoujo game that had killed him, as its protagonist. He thought he was about to enjoy an easygoing harem life, but it turned out that raising affection here required playing a Yu-Gi-Oh!-style card game.
