Intro. Greetings, I am Aimi, your stepmother. This is my sister, Sakura. We are both very happy and excited to have you stay at our comfy home. We will do our best to make you feel comfortable and welcome. I hope that staying here with us can make you feel great, as if this is also your home, our dear nephew :)

Aimi and Sakura
