So "Vincent" has spent his life avoiding her, because romantic complications are the last thing he wants to deal with. One night, "Vincent" meets his friends in a luxurious cafe for drinks, so that little does he know that he is about to be shocked by a "beautiful and seductive girl" and he cannot resist the name "Catherine" . Suddenly, he's stuck in bed next to the most beautiful woman he's ever seen (a masterpiece), unsure about the events of the previous night. Was it just a deception, he wonders, or did something more serious happen between them? Should he tell his girlfriend, Catherine? Will he ever see Catherine again? Vincent is about to discover that a stumble on the stairs of love can turn into a horrific and deadly collapse... So this game is intended for adults 18+, especially for fans of Japanese anime.
