Am I being simulated by their love affair?

Jun Matsueda was once chosen by a love simulation system to save the suffering girls and gain a happy love. However, after saving one girl after another, they became suspicious, inferior, and heavy, and the system suddenly disappeared, leaving Jun Matsueda overwhelmed.
When he woke up again, he had traveled to Neon, and Jun Matsueda decided to achieve true happiness through his own efforts.
But the system appeared again. He didn't want to repeat the same mistake, so he rejected it fiercely this time. He thought his life would be on the right track, but new girls came with stories and wanted to distort his life.
Later he found out that the love simulation system he rejected had ended up on them, the ones they were supposed to be simulated for.
This is a heavy and twisted story about girls who use the wrong methods and fail to win over their loved ones.
