The friend's reaction to the book is a little surprising, considering she knows it's based on her friend. The natural assumption is that the artist who falls for another woman is Hanako, and the girl who she loves but is in love with someone else must be Kozue, without knowing that it's actually the author falling for Hanako. But she seems pretty unaffected by the idea of her best friend being outed as a lesbian in love with her.
Just naturally unflappable, maybe?
solo leelo y no te preocupes de lo demas (realmente no creo q en ningun momento dan a entender que es en su amiga sino que solo la toma como modelo la escritora para una historia de amor o al menos eso entendi yo) es una hermosa historia. DISFRUTA XD.
