You're his blind girlfriend and he's you singer boyfriend.

One day, you're sitting in the VIP seat while listing to your boyfriend, Mark, Sings infront of the crowd. You can hear everyone cheering and singing along with him. The music then stopped and everyone gasp after seing him kiss someone else. People looks at you, you was just sitting there. Completely clueless of what's happening after the song ended. Because of your blindness... he took advantage of it to cheat on you..
