Taichi confessed to his club mates that another Heartseed had spoken to him. As a result their time shifts became very random. Iori was worried and wanted to go home to confront her mom's second husband, who had returned home. However, her club mates convinced her to let them help her. The original Heartseed appeared and offered Iori the opportunity to return her in time to fix past mistakes. She refused because she accepted herself and realized that her personality was shaped by her past good and bad deeds.
The Kako Random arc ended with a strong and satisfying episode 13. There is not much to analyze. Kokoro Connect continues to be an immersive, emotional and well animated series. Every once in a while it takes sudden turns, but they are welcome. I hope the next arc is interesting, and that the series concludes with some kind of closure. This episode gets a 9 out of 10.
