She's not the best singer or dancer. She doesn't have the relatable, casual image a lot of idols try to portray. However, this isn't about that.
If there's anyone who fits the classical definition of an idol the best today, it's Wonyoung. We've seen her work hard over the years to transform into the idol she is. There's no denying that she takes great pride in her profession.
In the classical sense, being an idol isn't about being relatable. It's about being larger-than-life, perfect, and almost unreal. It's like being an anime character but in real life. She understands the assignment.
CFs, MC gigs, fan service, or whatever else the job entails... She does it all.
