So. Girl A wants to know about Girl B's love life because Girl B won't share. Girl B still won't say anything, Girl A makes all kind of random guesses through the school day. At the end of the day, they're talking to Faceless Boy (There's a pun with his name being close to "handsome"), and a determined Girl B hold Girl A's hand while he talks. Then they walk home, Girl A is cutely flustered and Girl B is commenting to herself how easy Girl A is to read. I feel like the title is from Girl A's perspective about not being able to read her friend.

I'm going to feel so dumb when I'm shown what the title is. Because it's right there.
