i have been saying Chaewon is a dark horse since her P48 days and people wouldnt believe. Her center role in To reach you further proved that she isnt just a decent vocalist. She has the STAR factor.
Luckily she shined so much in Fiesta and from that point onwards you can see the label pushed her more as the vocalist. She has overtime grown to be more visible and outstanding from the group of 12 girls. SSOS, Panaroma, DDDance showed her vocal ability, the group isnt just yuri but has people lime Chaewon as potential main vocal.
She is super versatile + her experience in iz*one give her edge for having good stage presence and facial expression. She should be the face of the group (if she not already is). In fearless, she totally dropped her bubbly vibe and turned into a mature sexy lady. But off stage, she is still bubbly and lovely. Chaewon 4th gen best all-rounder to be honest
