She started playing the intro of our song, plucking the strings carefully with her delicate fingers. I watch her through the monitor of my screen as we practice together through Skype on my Mac.

Practicing had always been my way to be better with the things I do. Even if it's something not for me, once I put enough focus and concentration, I'll be able to do it.

For me, nothing can't be learned.

Well, it's not my first time to rehearse songs for a certain performance, but... it's the first time I'd done it privately with someone I'll be performing with.

We had another practice with the group of musicians, 10 cm, and Jihyo yesterday... somehow like a dry run but we were advised we'll have another practice that'll be on stage on the day of the event.

She lifted her head and turn her gaze to the screen, looking at me, signaling the start of the song to where I started off singing slowly while my guitar rests on my lap.

I noticed she smiled softly then bowed her head again to concentrate on the strings that play the melody while I sang this kind of melancholic yet dark melody, a song about an excessive fixation on love.

We've basically memorized everything to perfection already.

But when we got to the chorus...

"I'm creepin' in your heart babe..."

She suddenly sang Jung Yeol's part which I back-voiced. It surprised me, given that we don't want to get used to singing other's parts, we avoided the lyrics and just hummed or sing inside our heads. But her voice which is several tones higher than mine blended perfectly with mine.

We've already harmonized on the other songs but not in Monster and she did it easily, perfectly.

We did not stop until the end of the last song but as soon as we finished, I immediately clapped my hands to which she also claps hers with her usual shy demeanor.

"Uwah... that was great!" I continued clapping.

"Thank you so much for your time, Chanyeol-ssi. Now I'm confident I'll be doing well on our performance." She bowed and smiled.

She had asked if I still get nervous about every performance and to be honest, I still do. Tho most times, since I'm with my members, that anxiety is exchanged by the enjoyment of performing together. It's always fun, especially with the loud cheers of our fans. And that is exactly what I told her.

"I didn't expect you'll sing sunbaenim's part. That surprised me... and it's really great." I said, smiling at her.

"I'm sorry." She shyly waved her hands in front of the monitor, "I couldn't help but sing it. But thank goodness I was able to harmonize fast with you."

"You really have a beautiful voice, Chaeyoung-ssi. It's very attractive. Gives me goosebumps sometimes."

"Goosebumps? Creepin' you out?" She asked, giggling. "It's because it's cold already. Please bundle up."

"It wasn't the cold. It was goosebumps from being overwhelmed. Do you get that when you hear a good song? This time, it's because of your voice. I really like your voice."

"Thank you." She muttered, looking down on her guitar again with a soft shy smile that makes her cheeks puff cutely, looking like that of a chipmunk's cheeks full of acorns.

I have to admit, after that practice, after that formal introduction with her, I immediately checked her public profile through the net and there was a lot about her and her group.

They really are the monster rookie group and a lot is expected from them. But one article had made me thinking...

We all know most agencies banned dating amongst their trainees and artists.

"Chaeyoung-ssi, uhm... were you not in trouble when I asked for your SNS?" I asked.

Not that I was thinking of anything about dating. It's just that, I may have unknowingly caused her trouble because I wanted to get to know more about her.

"My manager didn't notice we exchanged information, oppa." She answered then pursed her lips immediately.

That word just slipped out.

A smirk formed on the side of my lips while a brow slightly raises as I asked, "Oppa?"

"Uhm, sorry." She then panicked in embarrassment, hiding her face behind her hands.

"It's alright." I chuckled. "This may get us closer and become good friends. I don't mind you calling me oppa."

To be honest, I'm masking my nervousness through my confidence. Well... maybe because she's only on the screen. I know I won't be able to move freely if she's really here.

"Really? but.
