Series is so good but volume 15 is such a let-down. I waited forever for this one and it's so uneventful

This was so sweet to read, and mostly realistic! I also really liked how her co-worker ended up with someone too. I didn't really like how Kazumi completely lost her supposed tomboyishness right after the initial schtick, and how she was a completely passive gf, and how the sex was somewhat censored. I would've also liked to delve more into her co-worker's romance. This is still a good read tho
