In the first one I hated Sasatani because there was always that little fear that either Yamashiro or Okumura would cheat (thankfully they didn't) but I didn't like how Sasatani was so arrogant. In this one I could tell his arrogance was meant as a shield. I loved the new Kei that was introduced! Although I couldn't help but wonder sometimes why he didn't just kick Sasatani to the curb because Kei deserves so much better. And then when he did I found it amusing that Sasatani actually showed his grief over the possibility Kei would leave him. Still love this series.
