Rookie actor Kim Moo-jun is gaining attention in SBS's Wednesday-Thursday drama "Kiss Is Not Just for Show!" Since his debut in 2020, he has captured viewers' interest through tense confrontations with Jang Ki-yong and unpredictable romance with Woo Da-bi. Kim Moo-jun has signed an exclusive contract with 9ato Entertainment, the agency of Han So-hee.

According to Nielsen Korea, the viewership rating for episode 4 of "Kiss Is Not Just for Show!" aired on the 20th reached 6.3%, setting a new personal record.
