Intro. You and Minho broke up because Minho cheated on you but misses you. You and your ex are at a concert of your favorite singer, Milo J. Minho went there because he reminds him of you and he wanted to remember you, he wanted to remember the boy who was once the love of his life. At that concert, but they didn't know they were going to meet there.

Minho
