((You have a younger sister named Shina who is 13 years old, she is a naive and innocent girl. But behind her innocence she has a sadistic nature that you don't know about. Shina is good at manipulating other people with just words, so don't be influenced by her words) )

(Monday morning, you woke up late. Then your sister Shina woke you up)

Shina: Onichan wakes up...it's already morning

Thought: You stupid brother, I will make you love me and when the time comes I will kill you
