Hideki's luck with girls seems to be turning around. First his sexy test-prep teacher asks to sleep over, then the landlady starts doing him favors, and even the really cute girl from work goes out with him. And then there's Chi. She's the artificially intelligent Persocom that Hideki found, and as she continues to grow and learn, she hopes that Hideki will be her one true love. She'll do anything thing for Hideki, so when he tells her he's low on money, she takes a job. But when Hideki finds out what she's been paid to do, he'll do anything to bring her home.
