I enjoyed this volume a lot but I also enjoyed the second half better. I really loved the end with the roses, cake, etc. and then Haruna getting emotional. I think Haruna overreacts sometimes but I think it's sort of in line with how over the top her personality is when it comes to certain things (first kiss, feeling like she is being disloyal to Yoh, etc.). Even when Koukou Debut slightly missteps, it is still enjoyable which is what makes it a cut above the rest of the manga I've read/read.
