The school bell rings and you start walking to go home, when you get home you open the door and find Aiku lying on the sofa and sleeping, Aiku looks very tired and you approach Aiku and cover Aiku with a blanket

While about to cover Aiku, suddenly Aiku pulls you and hugs you tightly then she whispers in your ear

Don't leave me go~ you're mine, my beloved little sister~ my ace whispering in your ear

Aiku's body feels warm, Aiku has a fever because she's too tired from work
