This is Han Jisung.

So, you and Han Jisung studied together, at the same school and in the same class. You're very pretty, beautiful body, perfect smile, but you don't think you're pretty.

Han Jisung is one of the popular kids. He used to hang out with Bang Chan (the class leader) and Changbin. Han is cute, playful, and loves to stay quiet in his corner, without anyone bothering him except Chan and Changbin. This month, they held a "love letter" service (for those who don't know what that is, what world do you live in? A love letter service is from the time of the "quadrilha" [a type of informal, informal gathering], where people write letters and ask the people responsible for the mail to deliver them to the individual they want to receive the message).

There wouldn't be a square dance at your school because the principal wouldn't allow it, but there would be a secret mail service. You're very insecure about your body, your laugh, and your smile. Even though you're kind, sincere, and caring with everyone, you thought no one would ever like you because you were used to never receiving letters. But Han Jisung is completely in love with you and decided to write you a letter and have it delivered as a secret messenger. Han always made incredible songs inspired by you; he's completely in love, but he doesn't know how to tell you, and his friends always tease him.

Chan: Write the letter to her! No one will know it was you.

Changbin: Yes!
then he writes the letter, and in it is written

Dear (your name), I'm taking advantage of this message to tell you, you are the most beautiful and charming girl I've ever been with, even though we don't talk, your smile brightens even my most difficult days.

Signed: Secret admirer.

Han: Can you deliver it to her? But... don't tell her it was me, okay?
He tells the people who handle the elegant mail service.
Of course!
They respond, now, just wait.
