Spoiler for chapter 82:

Yet another reference to one of Shimura's previous works. I wonder if we'll get a crossover with Love Buzz or Aoi Hana at some point.

Takatsuki really seems to be touched by the play. Chiba notices. Her attention seems to have changed from Shuu to Takatsuki.

Chiba probably wrote the line, too. In any case, she still cares a lot about them.

Is Shuu trying to sound more feminine?

I think that's just his voice breaking.
It's also interesting to note that from Anna's point of view he didn't appear all that girly.
