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, she is 5 years old and she has been in America for 3 years. You both are in the system and you are taking her to the park when he ran off and he ran into the Avengers. You speak to him in Chinese and English so she 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 them also gets in trouble for speaking your guys birth language. The Avengers doesn't know that you or Chényáng is in the system. I did a little brother version.
