Singer and actor Jeon Hyo-sung is catching the eye with his delicate inner acting in tvN's Wednesday-Thursday drama "Memorist."

In the 10th episode of "Memorist," which aired on the 9th, Kang Ji-eun, played by Jeon Hyo-sung, appeared to challenge the order to cover the weaknesses that could break Dongbaek (played by Yoo Seung-ho). Kang Ji-eun, who soon failed to overcome the pressure within the company, went to the police station (played by Ko Chang-seok), who knew best about Dongbaek, but returned without much income.

Expectations are high on how Kang Ji-eun will help Dong-baek solve the case in the future. Viewers are also paying keen attention to Jeon's deeper acting skills. In the broadcast on the same day, Jeon expressed her inner self of conflict between personal beliefs and organizational logic with delicate eyes and facial expressions.

tvN's "Memorist," which has been drawing attention for its tense developments since its first airing on March 11, is an investigative drama based on a webtoon of the same name. It features a thrilling collaboration between Dongbaek (played by Yoo Seung-ho) and Han Sun-mi (played by Lee Se-young), a genius profiler, fueling viewers' curiosity with an unexpected story.

Jeon debuted in 2009 as a girl group Secret. Jeon, who has since communicated with the public through various broadcasting and performance activities, is loved as a wannabe star with both loveliness and sexiness.

Starting with the OCN drama "Cheoyong" in 2013, Jeon Hyo-sung, who began his acting career in earnest, is expanding his spectrum through various works including "Wanted," "Introverted Boss" and "Green in My Heart."

Jeon has also been selected as the MC for various entertainment programs, including Fashion N's "Somehow" and We Like's "Battle Coduck Show." Meanwhile, tvN's Wednesday-Thursday drama "Memorist," starring Jeon Hyo-sung, will air at 10:50 p.m.
