Hi Guys, I tried to look at songs that can fit to be this story's OST. I only found a few songs that are perfect. They are English and Korean songs. I just don't know how to put music in the stories. But when I was writing this, I have always wanted to embed these songs. 

1. Baby Steps- This is a song that best describes how Sulli felt like after she confessed her feelings for Minho. This is when she was trying to touch Minho's heart so that he can fall in love with her.

2. How Did I Fall - A very lovely ballad that tells a story about how a sister-brother love turned into falling in love. This is best fit with Chapter 15 when Minho realized his feelings towards Sulli.

5. Four Seasons of Lonliness - This tells how a man feels loneliness on all four seasons missing the woman he loves. During the 3 years that they were apart, this song would best express how Minho felt.

3. You Wouldn't Answer My Calls - This tells a story about how a man lost the girl that he loved. How he would wait outside the girl's house just to have the chance to say sorry. And how the girl is now treating him like a stranger. Though it breaks his heart, he will wait patiently. This is most fit
