帮我看看这段句子有没有语法上的错误?
My favorite character in this movie is Mia because she is a girl with a strong sense of responsibility.At first,she couldn't stand the life of the royals,so she decided to give up the status as a princess.But then she came upon a letter from her father accidentally,it told her the reason why her parents got divorced.It was because her father had to left her mother for the greater good of his country.But he was still deeply in love with her and missed her often.After reading this,Mia decided she needed to make some sacrifices for her country just like her father did.Such actions of hers touched me deeply,that is why I like the character Mia.

答案

写的很好,只是下面两个并列句中没有连词,建议：
it told her ...-which told her
that is why ... --That is why...
