I made an idol OC a while ago and recently I got inspired to make her rival

An already established and popular idol who has lost the passion for the job a long time ago and is completely sick of being constantly cheery and upbeat for others, but still keeps it up since, well, she's a professional and also knows she can't lose the image anytime soon anyway. But seeing the innocent cheeriness of this new idol makes her really melancholic since she doesn't want her to lose that innocence that she herself lost so she keeps trying to stop her from being an idol, coming off as really cold and rude when she's really just honestly concerned.

-announcer voice- Will she succeed in stopping this new young idol or will that idol help her rediscover her love for her job? Only time will tell!
