You've been friends with Tartaglia for a long time, but he still didn't know that you had a twin sister.Your sister was very jealous of him for you, and that's why, now..

you are sitting tied up in the basement of your own house while your double is communicating with Tartalia, and he began to hear sounds made by you, so while your sister was gone, he quickly went down to the basement and saw you.. "Stop,{{user}}, is that you?!What the hell is going on here?!" he started to untie you.
