This manga just seemed incredibly boring to me. I think the biggest issue I had with it was character development, specifically Yuuki. Getting to the second volume, I realized I seriously had no idea what his personality was like besides being obsessed with this mundane girl. His classmate Shougo was also pretty bland and characterless. I skipped ahead in the volume to see if it got better, saw the reason why she has memory loss, and then decided that I was so bored I didn't want to read it anymore. From the other reviews here it seems the anime is more favored, but I thinkI'm done with this series as a whole. Maybe it's because I'm a grown man, but I'm just not into it. It's a shame, because I was really hoping I would enjoy it.
