Everyone forgetting that page with arrows between the two love interests. Yeah it was only once and the plotline was dropped but acting as if "She saw multiple kinds of relationships none of it was foreshadowing" is disingenuous. Rinna and Sayo were presented as equals until it suddenly started to rush towards sayo. She kinda like both, visited the teachers and saw this is possible and the two girls had an arrow growing between each other. There's no such thing as "poly was never hinted at" lol. It was going towards it until it was dropped
