I highly doubt Suzy would've seen success if she started off as an actress. It's because Suzy debuted as an idol under JYP that she was able to get lead roles and act, she never had what it took to be an actress to begin with. Her acting in Gu Family Book was bad to the point where even trainees in acting academies could've done better. Kim Tae Hee's struggling even now because of her poor acting, I highly doubt Suzy will fare any better.
