If Hiwatari had used her real name, Shima would have come out and told him about her, he doesn't know a lot of Shima's past, only the three girls know what really happened in junior high school, one because the girl came up to him and gave him a hard time, while she was changing clothes, the second he told when he turned down her confession, and the third when she asked him while confessing. A flag was set when the props were broken that the male lead is going to be out of the play.
