That's miyuki.
Touched huh... I guess that's a way to look at it... I'm in total agreement now that it was Miyuki saying the "believe... Huh" but the Huh to me was probably 'ne' in japanese I need to the raws. but if it was 'ne' then it could've been more sarcastically inclined. or at least I wouldn't go as far to say that Miyuki was touched, maybe it was more questioning how Sawamura can still believe in him, or that Miyuki possibly feels that he doesn't deserve that belief... it's like a weight on his shoulders... dunno so many ways to interpret it ;-)
Ch45 pg5 ( http://www.mangago.zone/read-manga/diamond_no_ace_act_2/bt/aed40cfe2b29fb6d/Ch45/pg-5/) The bottom left panel, who is saying "Huh... 'Believe'" Is it Miyuki or Sawamura?
I get the feeling its Sawamura, but then I'm not sure, because if it is Sawamura then it feels like he is starting to question his belief in Miyuki, it's almost as if he says it sarcastically, which doesn't really match Sawamura's character. But I so hope that it is Sawamura starting to finally wake up. I'm tired of reading about everyone taking him for granted.
Anyway opinions? Miyuki or Sawamura talking?
cheers
