Takamine - Dense and cowardly. This adorable little idiot probably hasn't crystalized her feelings yet but instinctively places herself everywhere Sakura is.
Actually, Takamine isn’t so little. jk!
Seriously, I agree with all your points and I thought this one was especially well-expressed. Takamine seems to keep all her feelings at arm’s length (at best).
And sometimes what looks like “cowardice” (OK, is cowardice) is also a function of a kind of emotional intelligence, of understanding the potential stakes involved in putting yourself out there with all your vulnerabilities. It’s hard enough finding good friends to go ahead and risk those relationships by changing the terms to romantic.
It’s also not easy writing such feel-good, wholesome yuri with an edge of real emotional drama. It’s nice to see it done well.
