Teenage Soulmates

Nishimura Riki, my brother's best friend since freshman year in high school! They both bonded over the fact that they were born in December in the year 2005, crazy right? But hey, at least I got my space. Emphasis on got. When Prince told Riki he had a twin sister, me, Riki just had to meet me. When he did, we clicked fast. All of us became a little trio.
Until the trio broke...

I thought it was going to break when Riki was becoming a trainee under BigHit, but then my brother joined, then I joined. We all got to train together, so the trio didn't end. Not until, I hated Riki...

I got eliminated to Ground a couple times, and Riki was just praised and the perfect dancer. I was jealous as hell. I started to hate everything about him. I wouldn't even look him in the eyes.
Worst part though? He had a crush on me.
Second worst part? I hated him for years.
Finally worst part? When I fell, it was late...
