Have I been simulated by their love?

Jun Matsueda was once chosen by a love simulation system to save a suffering girl and have a happy love. However, after saving one girl after another, they became suspicious, self-abased and burdensome. The system suddenly vanished, and Jun Matsueda was overwhelmed. When he woke up again, he had already been transported to the neon lights. Jun Matsueda decided to achieve true happiness through his own efforts. But the system reappeared. Unwilling to repeat the same mistake, he firmly rejected the system this time. He had thought his life would be on the right track, but new girls came with stories, trying to distort his life. Later, he found out that the love simulation system he had rejected had ended up on them, who were supposed to be the simulation subjects. This is a story of heavy and distorted girls who failed to win over their beloved by using the wrong methods. (Distorted text, warning of insanity, warning of rivers of blood)
