The next day, Jieun was not present in the classroom. Even Kikwang, Yoseop, and Suzzy no one knows what happened to Jieun. They contacted Jieun's phone but unfortunately, it seemed not active.

Having no other choice, they decided to meet her at her home. They were welcomed by the guard at Jieun’s house.

Kikwang: "Can we meet Jieun?"
Guard: "Miss Jieun already left for Japan this morning."
Suzzy: "Eh, Japan? What does he mean?"
Yoseop: "Jieun not say anything yesterday?"
Guard: "Miss Jieun entrust this letter to you."

The guard handed them four envelopes which Kikwang curiously looked at.

Suzzy's POV

I opened the Jieun’s letter for me.

To Suzzy:

When you read this letter I may have reached Japan.
I’m sorry for not telling you about it.
You must be very mad at me ...
(Or happy because your rival to get Yoseop is now gone?)
Hehehehehehe ..... (Mian. .. I'm just kidding).

Anyway, I want to apologize to you because I have made a huge mistake.
Honestly, I was the person who littered on my uniform with spray paint.
I put the spray paint cans in your bag.

Hyosung was innocent at all. I also wanted to confess that I was the person who sent a brief message to you.
I'm the real two-faced ...

I realized that I’m the one wrong. I'm sorry Suzzy.
Thank you for being my friend.

Good Bye.

Song Jieun.

Yoseop's POV
To Yang Yoseop
I'm very happy to be friend with you all. But I had betrayed our friendship. I feel differently to you. I like you as a man, no longer as a friend.
I want to admit one thing.
I am the person who littered my uniform with spray paint.
I'm a keep spray paint cans into a bag Suzzy.
Hyosung is innocent at all. I also wanted to confess that I was the person who sent a brief message to you.
I'm the real two-faced ...
I realized that I was guilty. I'm sorry Yoseop.
Thank you for wanting to be friends with me.

Good Bye.
Song Jieun.

Kikwang's POV

To Lee Kikwang,

You are the one who understands me the most.
In times of difficulties, you’re always there for me.. I'm really lucky to have a friend like you.
Although, I’m also sorry if I unknowingly hurt you.

The truth is, I was not happy when I found out that you had a foster sister.
I began to hate Hyosung. Therefore I made a big mistake.

You know?
I was the person who littered my uniform with spray paint.
I just put it on Suzzy’s bag so you all would think that it was her.

I also wanted to confess that I was the person who sent a brief message to you.
Hyosung is innocent.

I'm the real two-faced ...

And now, I’m guilty. I'm sorry Kikwang.
Thank you for always being my friend.

Good Bye.

Song Jieun.

Hyosung's POV

Hyosung, I'm sorry. I had slandered you. I actually hated you.
My jealousy had caused you to be hated by Suzzy.

But you still helped me. You kept your promise.
And by that, I just realized that you are really good person.

Yoseop and Kikwang still believe in you.
They both must really like you. (I feel envy on you, hehehehe)

By the way, try to smile more. Surely you must be so beautiful.

Once again I apologize for all of my mistakes. I hope you’ll forgive me.
Thank you for keeping your promise.
Good Bye.

Song Jieun.
