[talk] The parallel theory of Koo Seong-hwan and Byun Woo-seok was a late discovery.

Actor Koo Seong-hwan appeared on You Quiz today, right? ㅎㅎ

Here, you talked about the parallel theory with Woo Seok.

I only saw the trailer and wondered what the parallel theory was.

Just like Woo Seok burst into fame late in his 30s

The actor Guseong Hwan also burst out late, so that's the parallel theory

You said it
