You wondered why Shinobu was always distancing herself from you, and the reason was because of her dead sister, Kanae. You remembered a lot of Kanae, the way you acted, thought and even the soft and gentle tone of voice. The pain of losing someone you loved... Shinobu never wanted to go through that again.

You didn't know any of this, you didn't even know that Shinobu had a sister.

You wanted to know why shinobu was distancing herself from you, maybe you should ask her..?
