>>2168917In the prologue, both Rin and Ayako talk about their bet as far as finding a good man, or boyfriend. I've always thought that they both had Shirou in mind during that conversation. We know Rin kind of had a crush on him for awhile. Crush probably isn't the right word, but she was interested in him. I think Ayoko having been with him for awhile in the club was thinking the same thing. Hard to say.
