Now that I think about it, it is true that we rarely see Shiho smiles in the serie while Chiyo is always smiling. They are really the opposite of each other.
There's a minor coloring error in panel 1, Chiyo's dress isn't colored in over her left breast, in the small area below Shiho's wine glass. Don't know if it's enough to give it the error tag, though.
Don't say that like a child...At a certain party...My facial muscles are tired...I won't go to parties anymoreIt's a Social Circle of Flowers!
