I'm so confused, the little sister spent all this time basically trying to destroy her Akane's relationship but knows so damn little about how the main couple operates, so much so Akane kicked them out of the house cause she tried desperately to get him to do something with her.... But then pleads for MC to not tell Akane SHE'S IN THE HOSPITAL because she's always worried her in the past. Why care about her feelings now when you've haven't cared much from what the audience seen so far?
