At the start it would appear that this story will only be about fun and good moments for the "club" members, but after a brief fun during the first ova, the story turns out to be more deep and tense. Rika now feels strange and distant. And even feels that the same tragedies of the "past times" will occur, feeling that destiny is something that can't be changed in the end. She thinks about getting involved and try to solve those mistakes or just giving up to that tragic destiny.
