Hyejin's POV
I peek from the door but I can't see anything. It's pitch dark in the room. From the voice, I think the owner of the voice is a girl. The piano started playing a sad melody, she harmonizes her own voice with it.

I have nothing else to say
No other reason or excuse
I know it’s meaningless
But the end is always like that
Don’t ask me anymore
Don’t ask me since when
I don’t know why but
Everything from when we were together
Shows that things were hard

The way she expresses the song, it's like she is saying what she really feels now. She is so sad, hurt and she badly wants to cry. I can tell it. However, at the same time. I want to sing with her even though I hate singing. 

That night when I was in your arms
That moment when we kissed
All of that remains as a scar
That I can’t tell you about anymore
All of that is a burden to me
Don’t tell me that
I can’t help how I feel
It was really hard even up till today

Daebak. Her voice sounds so soothing and angelic

"Hyejin!" when I looked back Moonbyul unnie is suddenly behind me "Your taking too long. Where is Wheein?" she asked
"I think she is still in the restroom" I lied

I noticed the piano stops playing and I can't hear her voice anymore. Maybe she heard us.

"Let's just go back" thinking now, I think Wheein need some time alone

"Wheein congrats! You're so amazing, you won on your first competition last week" I ruffled her hair "See! I told you, just have some confidence to yourself and you will win" I said
"It's because of you. You are my mentor and you are always by my side, that's why I'm gaining confidence but," she looked at me and smiled
