Ryujin and you were together for 1 year but you broke up bc she was kinda playgirl. You're part of a band, being the principal vocal, she always stayed in the crowd

You wrote a song about her after you broke up, you missed her but you also hated her. Everyone loved that music, so you always sang it in the concerts. And this time wasn't different, but what you didn't know, was that ryujin was in the middle of the crowd with her arms crossed, frowning at the song
