I am confused about the ending. Did Tana smile because she now accepts her change and has hope that someone will love and accept her in the future like how Yousuke accepts and loves Rika? Or did she smile because she believes Murase loves her because he was willing to accept her and touch her alien? Did Murase cry because he was sad for his "friend" Tana? Or did he cry because he has always loved Tana but she never recognized it (along with us readers)?
