Although
the chapter is about Utsusemi, the main character appears
to be a friend of her (her Go opponent), which stays
nameless but is identified as her stepdaughter and the
daughter of the Governor of Iyo. The situation is about
waiting, mistaken identities (Genji ends by spending
the night not with Utsusemi but with her stepdaughter) and
crossed feelings.
The
lady in the image most probably is not Utsusemi but her
stepdaughter, and the feeling it conveys seems to be
related to the aftermath of Genji visit and to the waiting
for the message from Genji (which was customary after a
romantic meeting), a message that never came.
