Why some people hate this series? I admit I was worried at first for the male protagonist and its possible implications (harem, etc.) but after reading a bit realized that it's just good old nanoha. And striker's style which I love the most.
Actually it is THE ONLY semi-official pairing from K-On!. In the first season the others notice mugi giving odd looks to sawa-chan and ask her if she loves her? And she responds I was just thinking girl with girl is very good! :D
