This drama got one of the worst 1st episodes. I really didn't like the cast's performance. Extremely superficial and full of amateurs. It's impressive how 99% of similar drama templates turn any setting into a business setting regardless of whatever the beginning was, and this drama is no exception. You would think the setting would be in this "school" since the drama advertised FL as a teacher at a traditional Korean school and also the poster/synopsis seems like it but no! After few episodes, everything become about business with the usual cringe shenanigans in every similar setting where they fight/sabotage/expose each other till the end. The "twin" was seriously cringe, unbearable! How many were killed? Simply, there wasn't enough justice anyway. Don't watch!
