Voiceless.

Aria is a super popular idol. People said she has the voice of a siren as it can hypnotize everybody. She's also very pretty, good looking and doesn't lack money. People call her "the favorite daughter of heaven". It may seem like she have it all but deep inside she's a lonely woman.

The class president on her high school has planned a reunion. She met her old classmates as well as her high school crush.

Many things have changed but she still can't bring herself to talk to her middle school crush. She was sitting beside him and was shocked when she caught him looking at her face attentively and he asked, "Why are you voiceless with me? do you really hate me so much?"
