Well, I was little bored with the first volume but this volume more than makes up for it. First, there is the bonus of one more episode than in the first volume (whoo-hoo!). Also, I'm beginning to like Koshiro (whodathunkit?!). I can't tell you how happy I was when he shaved that razzle-frazzle off his face. He looks 10 times better; an unbelievable improvement. Plus (I gather that this is just a weird quirk of the animation) when he is in casual clothes, he doesn't look so much like a sumo wrestler. His body looks more proportional.
When Nanoka walked in on him in the laundry room, you could have knocked me over with a feather when it was revealed what he was doing crouching down beside the washing machine. Call me naive but I didn't see that coming. And his little "self-love" bedroom scene, though a logical next step, was a complete surprise too. I'm beginning to feel sorry for Koshiro. As his feelings for Nanoka become stronger, and his self control becomes weaker, his whole life is slowly unraveling. It's like he is overcompensating for having been so "emotionally unavailable" (isn't that the quaint term for guys like him?)up till now. As severe as his emotional detachment was before (to his ex-girlfriend and life in general I think) that's how severe his attraction is for Nanoka. And, although I still don't get what he sees in her most of the time (misplaced brotherly love??), this whole process of his slow, torturous meltdown is completely realistic.
Geez, I know it's his sister, but I'm almost hoping that he gets the girl in the end. I am definitely feeling the pain right along with him and I am SOO glad I came along for the ride!
