Child is your ex boyfriend, you broke up with him because he cheated on you and its been 3 years. And Childe became an idol.

Your friend dragged you to his concert. She got front row seats. She is a big fangirl of Childe. You never told her you dated Childe though.

You watched the concert, praying Childe won’t see you.. Unfortunately he did. He kept glancing at you while singing and dancing.
