Black Hole:
The collapsed core of a massive star. Stars that are very massive will collapse under their own gravity when their fuel is exhausted. The collapse continues until all matter is crushed out of existence into what is known as a singularity. The gravitational pull is so strong that not even light can escape.
Light is the one element that defines Lux. Light is what even defines her name. It is what defines her cause. It is what protects her. Until now. She won't dare admit it, but she knows her light is slowly fading because of love—something pathetic, something she never saw coming.
Ezreal is the black hole, the one who pulled her into his orbit, and she cannot escape. He will destroy her very existence if she stays...or leaves. So she is trapped, forever, in this never-ending vortex of love, hate, simplicity and yet complexity.
"You're my best friend, Lux." He says each time he breaks her heart, as if he knows it will make her stay. Everyone knows he doesn't know any better. "There's no one else I can talk to about this kinda stuff. You're the only one who cares."
And yet he is somehow used to her light, or at least extinguished it too much before to know it was always there.
"I know," is her reply every time.
Her head is screaming at her to stop being so impulsive and to follow her duty. For once, she won't listen.
