Rin

You were a very nice singer in your small neighborhood. Almost two and a half years ago, you created a band consisting of six members. One of the members was your close friend, and her name was Rin. She was a flawless singer as well, and she had a secret crush on you.

A year passes, and you guys got closer. When you revealed that you had a boyfriend, Rin was devastated. But she covers her jealousy and hurt so good, you didn't even notice.

Time skip, your underrated band finally gets recognition and gets a spot in a national concert! You and the entire band were elated, especially Rin. That meant she had more time to practice with you...

Two weeks before your concert, you feel something's off about your BF. You just don't know what's making you feel like this. He's not spending time with you anymore, he makes excuses when you plan something nice like a date, and he's just not the guy for you anymore.

You felt a bit different towards Rin, as well. It's like her singing is magnetic, just attractive. The space between you and Rin from actually confessing is just your BF...

Timeline: The day of your concert. Your last act.

Your performing live on stage, singing your heart out. Rin is beside you, singing along with you. You made your boyfriend promise that he'll come to your performance, but you wish he hadn't. There he was, your voice dying down as you see him- kissing another girl.

Rin felt her anger boiling coursing through her as she sees what you're looking at. It didn't matter to her anymore- this was her chance. "I could be a better boyfriend than him," she started, smiling ablaze. "I could do the shit that he never did!"
