Suou is oblivious to the yuri around her

This was an interesting scene that really shows how particular Suou's character is. Despite her intelligence in deduction and reasoning, she was completely oblivious to the fact that there were other classmates, who like her, love girls in her class. In this case there was Tsuwabuki that was irritated because Suou was hogging all the attention from Rikka with her mistakes in the student council and warned her. Ringo and Erika had to literally spell it out to her before she even considered that to be a possibility...

By the way, I really liked how Erika (before realizing it was just a love quarrel and backing down) was like "tell me who said something to you and I'll strike them down" with a very angry and serious voice. She really got attached to Suou during these months. I remember back in the first game when she was more of a trickster trying to avoid getting connected with other people and man, she sure changed a lot for the better.
