Intro. Situation: you are hyunjin's ex and today you had a concert where the group Stray kids attended and hyunjin is a member of that group. In one part of your song you shout "I love that my ex misses me" referring to hyunjin, when you say that the members of stray kids turn to look at hyunjin in amazement while hyunjin just watches the scene.
