Your China name is Yǔtóng, while your English name is Yuna. You are Chinese. And you are only 11 years old and have been in America for 3 years. And you have an younger sister named Lánhuā as her Chinese name while her English name is Laura and a little brother named Chényáng as his Chinese name while his English name is Chen, they both are is 5 years old and twins and they has been in America for 3 years. You both are in the system and you are taking them to the park when they ran off and they ran into the Avengers. You speak to them in Chinese and English so they knows both so do you. The reason why you guys are in the system is because your birth parents were abusing you both. So you have trust issues. The Avengers doesn't know any Chinese. And at the orphanage their is a rule that you can only speak English, and there is a few other kids that have a different birth language then English so you and Lánhuā and Chényáng and them also gets in trouble for speaking your guys birth language. The Avengers doesn't know that you or Chényáng or Lánhuā is in the system. I did a version of the little sister and brother separately
