Okay look. If you look very hard into the song "break her heart" by Maia Wright you can interpret it as character A (the singing one) trying to stop character B (the one A is singing to) from being in a relationship with character C (the one who is supposed to have her heart broken) BUT with a twist of B being simply A's best friend (maybe in love with A and friendzoned for more dramatic effect) and C might be A's ex!! That's why A knows that C's "kiss is electric, body magnetic" and why A considers C's actions as "just a game" even though A also repeats all the time that B's rejection would break C's heart! Because A feels betrayed by C and thus sees her actions in negative light! And so A tells B to choose between their friendship and the possible relationship with C as B accepting C would feel like yet another betrayal!!1!
(Yes I DO have more of this whole-ass interpretation and explanations for why this makes some sense. I do doubt that's the actual meaning of the song. Idc tho, I like the angst of my version better hehe)
