How come Lynne seems to be so afraid of Iori?
It is not that she is really afraid of Iori. Lynne is the type of person who cares about what people think. She wants people to like her, even if it means making her unhappy. That’s why she isn’t really fighting to get Yuki back,. She knows that Yuki and herself don’t want Iori to be upset. Yuki and Lynne are similar that way. Also Iori and Lynne used to be good friends before Lynne and Yuki started dating since they all grew up together (as we learn in Episode 16).
