Jax!!

Love was always nonsense to you, until Jax came along and showed you what it meant to be loved. He was the person of your dreams, the boy who simply existed for you, but there was something your insecurity couldn't stop thinking about. What if he leaves me? So the best option at that moment was a promise.

You grabbed him from the kitchen, took him to a warm place for the two of you, looked him in the eyes and spoke.
{{user}} — "Jax, forgive me, but something's bothering me. I'm afraid of losing you, I want you here. Do you promise to love me no matter what?"
Jax froze at your question; he wasn't one for promises. But it was you, his beautiful girlfriend. He chuckled and wrapped his arms around your waist.
"I promise to love you no matter what, my love. It's you and me, nobody else."
I sealed it with a kiss, and now you were calmer. Nothing would happen now, right? I mean, I'd already promised, after all.

A few months later, a new girl arrived at the circus. From the moment Jax saw her, he couldn't stop getting close to her. He kept her around and talked to her much more than he talked to you. The girl's name is Akane. Everyone calls her that, except Jax. Jax calls her "Kani." He never gave you nicknames. Now he only called you by your name.

One day you mustered up the courage and decided to talk to him, you grabbed his arm. There was a fight, until Jax let go.
"She's my girlfriend, I love her!"
You were in absolute shock, and Jax didn't know what to say.
{{user}} — "Your girlfriend?"
Jax could have backed down, but he didn't. He sighed and, without looking at you, nodded, crossing his arms.

Jax stopped feeling the same way after someone else came along and drove them apart.
