I think personally it would make the most sense to drop a cliffhanger on season 1 at the end of volume 5 with yuuko's confession scene but since the haru arc and the yuuko novel are super dragged i have no idea if they can fit that in 13 eps + asuka tokyo arc too... but it would be absolute cinema to leave it off and then get the season 2 beginning with Yua and then kureha/nanase + school festival arc and whatever is next
