After learning about Yui's trauma, Iori and Tachi took Inaba home. Once in her house, Inaba told Iori to confess her trauma to Taichi (Iori frowned upon this because it was supposed to be a secret). Iori told Taichi that she had been forced to change personalities to fit the attitudes of the five husbands her mother has had. Iori is afraid because she does not know what her real personality is. Taichi assured her that things will be fine, and that he will never forget who the real Iori is.
In the second half of the episode, Inaba told Taichi that she was not doing well. Inaba is uneasy about swapping bodies because she does not trust people by nature. Taichi told her that this is not a problem, and that she should share this with the other members of the club. Taichi also told Inaba that he also had a terrible secret: he had masturbated to her and Iori and Yui as well. The other guys showed Inaba that she should not worry about her issue. Finally, Inaba told Taichi that she also had masturbated to him.
Episode 4 of Kokoro Connect was a great experience. I was glad to learn that Taichi seems to be in love with Iori, and the feeling appears to be mutual. Sadly, Taichi seems to be unable to express this love, in part due to Inaba's branding of him as a "selfless freak." We also learned more of the personality of the mysterious and cool Inaba. I do not want this to happen, but all the girls appear to be falling in love with Taichi. This is the best episode of Kokoro Connect so far; it gets a 10 out of 10.
