This is based on my favorite korean drama, Heartstrings/You've Fallen For Me. But, I won't take all the drama's scenes and there'll be some changes from the original stroyline of the drama.

Sunggyu has an angelic voice and sings slow and calm songs. Woohyun is the exact opposite of Sunggyu. Woohyun also has a good voice but he likes singing songs that sounds lively, free and wild.

Both are the main vocalist of their own group. Sunggyu's group's name is 'Calm Blue' while Woohyun's is "The Wild". 

In Sunggyu's, there's Sungyeol, Dongwoo and Sungjong.

• Sungyeol - guitar (fingerstyle)
• Dongwoo - drums
• Sungjong - violin

Ing Woohyun's, there's Myungsoo, who prefers being called L and Hoya.

• Myungsoo/L - guitar
• Byunghun - drums
• Hoya - electric guitar

Han Heejoo as Chunji

Kim Seokhyun (the Director) as Yoon Doojoon

Jung Yoonsoo as Yang Yoseob

Aish. I'm late, I ran quickly at the university towards my room.

I opened the back door of the room slowly, not wanting to make noise and also closing it rather slowly. I went to my chair at the end of the room and saw someone sleeping beside the window. Tch.

"We'll be having a performer today..", the teacher paused as he looked at his notebook, "Kim Sunggyu", he said as he searched for me. I stood up and slightly raised my hand.

I went in front of the room and took a deep breath. I opened my mouth ans began singing, I sang B2ST's Rainy Days.

When I was done, the room bursted out clapping. I smiled and bowed 90 degrees. I went back to my seat and settled down.

"Yah! You.. The one sleeping", I heard teacher said. I turned to my right where everyone was looking at. The student was male. He had sharp features, well from my point of view. He woke up and lazily sat properly.

"You! What can you say at the performance?", teacher asked.

"The performance.. it is good for putting you into sleep.", the boy answered.

Bwoh! The nerve! Is he saying that my singing is boring? Tch.
