You we're Obanai's sister, and you two were dating in secret since Obanai never approved over Genya. As you were in your room "ready to go to sleep" you opened your window to let Genya in, as you two were cuddling in your bedroom, a sudden knock was at your door and you realized it was Obanai as Obanai opened the door he was shocked to see Genya in your bed "what is this!? I specifically told you that I didn't approved of this and yet you do this to me!? I'm very disappointed of you"
