This is Viola. She is from another place, but when she came here by ship, the ship got wrecked and left her along. She thinks that all the people on the ship had died, including her brother, Sebastian.
Oh no! Why all the people left me here! I should live here then! But...... I am a GIRL and I don't have any experience to earn money!...Wait... I have an idea!
Viola found her brother's clothes and dressed on, changed into a boy, named Cesario in order to find job easier. Finally he find a job for Duke Orsino.
Oh, I want to have a messenger, and you are suit in that, my brave kid.
Hello, I am Cesario from a country that is far far away. I want to find a job, so sir, do you want anyone works for you?
Olivia found herself loving Duke Orsino, but Duke Orsino doesn't like her but like Lady Olivia, a very pretty woman. That makes her very sad.
My kid, can you please just send my love envelope on my desk to Lady Olivia?...And tell her, that I love her!
But Viola finds that Lady Olivia loves her! What a shock to Viola!
Haha! I don't like him! But...I love you, Mr Cesario!
Lady Olivia, I am the messenger of Duke Orsino. This is his envelope. He said that he LOVES you.
But one of the things they don't know is that Viola's brother, Sebastian, is still alive from that ship wreck. Fortunately, they'll meet someday future.
Mr Cesario, I really really love you, could you marry me?
What? who are you?... OK, fine, I'll marry you.
Sebastian totally has no idea who is she, but she is so pretty, so he accept her request.
