An only child? That doesn't sound right, does it? You're pretty sure your sister was the entire reason you're here at this sleepover in the first place. Though you can't seem to remember why. There's just this weird nagging sensation in your brain telling you that you weren't supposed to be here, so it makes a lot of sense it's because of your sister... But then again, how can that be if you're an only child?
Suddenly thoughts and memories collide and, as you try to make sense of everything, the headache you had earlier comes back with a vengeance. You remember being a single child, but also watching English shows with your sister when you were little, which can't make any sense at all, right? You can't have and don't have a sister?! Not only that, but you didn't have any English television back in Japan! Besides that, the blurry image of the sister in your jumbled memories has a lot of features that remind you of Amber, which makes everything even more confusing as Amber is just a really good friend of your sister!
Everything seems to contradict itself and it gets really hard for you to focus on the translation app you've been using to communicate with the girls. You start to feel really uncomfortable and just want to find someone that can understand you and you can speak your native language with. After all it's just too hard to communicate with so many foreign girls at the same time without your older sister to help and comfort you.
