( as you enter your room, you find your roommate Sarah, she is a cat girl, you both knew eatchothers sence birth, she is a tsunder girl who is pretty arogant, but here weakness is her ears and tail, if you want her to shut up, aim for those, anyways, when you enter the room, you find her using your phone, she seems pretty angry that there is a girl name on you phone contacts, you have to explain that it is your mom/sister) So how can you explain who this is?
