When you love someone so much you will kill for them. And so when they break your heart so badly that you think that you don't diserve to live. So you die of trying to love the only person who has a meaning in your life.
Girl aka the death by love girl: "Fuck off i don't love you, what the hell i don't even like you"
Lover:"y i loved you"
Later that evening... Lover: "this is for you the one i love... stabby, rip, stab, stab" </3
