She come to station right after the class, today is her first class, she decided to take time to study, preparing for college entrance exam. She come to take a look at her locker, the place where she put her secret, her love for music from her parents. She’ll transfer those things to her room since her parents now allowed her to do music, but..she must study hard in college. Then, she found her music book, she take it out then found out that one of her song that she couldn’t complete before the accident, now is complete..
“What is this?, it’s not my hand writing,” she said, “who wrote this?,” she asked. She take out all her things from the locker, “is there someone else who know about that locker?, I never told anyone about it though,” she said while walking to bus station nearby. She still have trauma every time she heard sound of train, so she is walking really fast. In the buss, she read the lyric of the new song, “it’s not me who wrote this, I couldn’t call this my song then,” she said then close the music book and take out the recorder, someone recorded the part of the song there, someone she doesn’t know,
“who is he?,” she asked, and keep listening to the song, “it’s good,” and play it from the start, “why I feel I heard this voice, who is he?, who  are you?,” she asked all those question to herself.
Eunwoo waiting for Sooyoung near her house, with sulking face. Sooyoung waving her hand to him when she see him,
“Why are you here?, mom at home, you can waiting for me there. She made something delicious today,” she said, Eunwoo looking at the paper bag she bring then take it, “it’s okay, I’ll bring it,” she said while trying to take it back but Eunwoo just walking, leaving her, “Hey…!!” she following him. 
Her mother smiling when she saw her only daughter taking out her things that she hide from her before,
“Someday, I want to hear you sing a song that you wrote…,” she said with smile, “did you wrote a lot of songs?.”
“I did wrote songs, but not really good song,” she said, “where is my lunch today, mom?,” she asked, then she see a lot of food on the table, “is there any occasion? Why there are a lot of food here?,” she asked, Eunwoo smiling,
“Mom just want to cook all the food that you couldn’t eat it when you were coma,” Sooyoung hug her, “come here and eat with us,” her mom told Eunwoo.
While Sungjae still focusing on his screen, writing lyrics then playing guitar. One of the member of melody band is there reading magazine,
“She did better than before, right?,” Hyunsik asked, Sungjae nodding without looking at Hyunsik, “are you happy that your song help her to rise her popularity?,” he asked.
“I’m not working by myself, it wasn’t only my sweat that creat her success,” he answer cooly, Hyunsik grinning, then continue reading the magazine, 
“Ah..abou that girl, my fans..how is she?,” he asked, then suddenly he stop his work, he lost focus after heard Hyunsik question, “why?, what’s wrong?,” he asked.
“Hyunsik-ah, I finished her song and placed the music book and recorder in her locker, but why I felt I want to give her in person.., why?,” he asked to Hyunsik.
“Because you want to meet her in person?,” he said, “hey, don’t tell me..you are starting to like her?,” after heard that Sungjae suddenly standing and running to him, “hey, what are you doing?,” Sungjae trying to shoot his mouth,
“Don’t say something like that with that loud voice in this place,” he said, Hyunsik getting rid of his hand from his mouth,
“There are just the two of us here, so, are you really?,” he asked him the same question, Sungjae sitting next to him,
“Ah, I don’t know, I don’t want something bad happen because of this feeling,” he said.
“If you really like her, then..you’ll be the bad one,” he said, Sungjae turn his face to him, “because you like your cousin’s cursh,” he said, Sungjae hitting his own head, “ahh.sorry for making you like this, continue your work, we’ll released album in 3 months..so finish it, okay?,” he’s saying while rubbing his back, “I hope your life right now will be great inspiration for our album,” he said.
“He want me to write 3 songs, so the other songs aren’t mine..for the 3 song, it’ll be finish today..your member can start practice it tomorrow,” he said then back to his work, “I heard Ilhoon will participate in writing lyric, right?, then you can help me to complete this third song lyric?, I’ll credit your name later, so your fans will be happy to see your name participate in writing,” he said, Hyunsik walking to him,
“And one of my fans is the Miss X girl, Park Sooyoung-ssi,” he’s teasing, Sungjae starring at him, “okay, sorry.”
Sooyoung’s laying on her bad, looking at the recorder that she get from her locker. She’s still curious, who’s the one who recored his voice here..who sing here..who complete  the song, the lyric for her,
“I would like to say thank you, but I don’t know who you are. Give me hint, who are you?,” she asked, then her phone ringing, from unknown number, “hello,” she pickep up the call, there is no answer, “who are you?, is there something I can help?,” she asked, still there is no answer, when she is about to end the call,
“Save my number,” a male voice said then end the call.
“I don’t even know you, how should I save it?, a strange person,” she said, but then she still save it, she save it as ‘X’ for his phone number. 
Sungjae walking to kitchen, he take out something from refrigerator, Eunwoo still watching TV late night, he ordered late night food. He still mad at him, they didn’t talk to each other since that day. Today, Sungjae want to solve the problem and want to act like before, because these day become really uncomfortable for him every time he get home,
“Eunwoo-yah,” he called him, but he still focus on TV, “this hyung called you, so I hope you’ll face me right now..I don’t know why we didn’t talk to each other since that day, but now..I want you to talk it out, what’s made you so angry?. Because I have conversation with her with your phone?, because that damn 5 minutes?, why?,” he asked, Eunwoo looking at him, “answer me now.”
“Just, when someone in one side love, then his crush suddenly getting curious to other person..that kind of thing?. She rejected me after my first confession 2 years ago and then we decided to become friend first. We are now friend, but then I feel someone trying to steal her..ah not actually stealing because she isn’t my girlfriend..”, he is correcting his words, “it feel like someone taking interest in her..it make me upset that she give response to that..,” he said, “so, I hope what I’m  thinking right now won’t happen in the future hyung,” he said then leave him.
Then Sungjae thinking of what Hyunsik told him this morning,  If you really like her..then you are the bad one. 
“I don’t know Eunwoo-yah..I don’t know it would be like this..I’m sorry for making you angry,” he said then back to his room. There he is reading a text messege from Sooyoung, “why?, in the middle of the night?,” he asked then open her text messege, 
I feel familiar with your voice, are you the one who
Complete the lyric of my song?, the one who recorded his voice in my recorder?.
After read that..he thought..how did she know that it was me..just by voice?, how did she recognize me just by that?.
