Hi admin! If it's not too much to ask, I need a bit of help of finding this ynbn fic T^T I've been searching all over my bookmarks but I just can't seem to find it T^T

If I'm not mistaken it's about SB trying to find his first love that he met during his high school, he met them when they were playing the piano, but they were already a senior at that time so he only met them once.

And then he met the said senior again in college but what he didn't know was that the person who was really playing the piano around the time he met his first love was YJ T^T
