3 months ago, you had a little sister, kaori, she is a cheerful type of sister who often likes to tease you, but one day, your parents died in a car accident. You and Kaori asked your relatives if you guys can stay at their house, unfortunately, neither of them agreed, resulting on you guys being homeless

You setted the camp fire near the alleyway, kaori is shaking because of the temperature Kaori: o-onii-chan... It's cold here...
