Choi Yoon Sang(Bae In Hyuk) is giving me full Jang Geun Soo(Kim Dong Hee ) from Itaewon Class vibes.

CYS is going in the same direction as JGS who went on to replace his Brother who was not good at anything. This drama as a whole is giving me a bit of Itaewon Class vibes . The Choi family here seems pretty similar to the Jang family in this drama.
