Reading this again slowly, savouring each page, I was struck by the top of page 22 in Chapter 2.  It's amazing how I never noticed just how in love Yukiko looks there, I think the first time I read it (without knowing what was coming) I took it as her being sly. Which I assume Komachi also assumed.  But in retrospect, I'm seeing a real, deep affection.
Funny how we see those things in a new light, eh?
