Lee Seo-an Shakes Up Succession War in Reborn Rookie by Revealing Ambition

As the JTBC weekend drama 'Reborn Rookie' races toward its finale, actor Lee Seo-an has emerged as a key figure turning the tide of the drama. With the hidden true nature of Naeun-se—who had previously appeared to be a quiet supporter—being revealed, the succession war within the work has expanded beyond a simple fight for an heir into a psychological battle surrounding the essence of power and desire.

In episode 10 of 'Reborn Rookie' aired on the 28th, Lee Seo-an, playing the role of Naeun-se, acted as a decisive variable shaking up the internal power structure of Choi Sung Group. While Naeun-se initially appeared as a cold-blooded executive helping his father Na Byeong-mo (Jeong Jae-seong), as the episodes progressed, he was revealed to be a character who calculates everything thoroughly for his own purposes, heightening the dramatic tension.

In the drama, Naeun-se led his father Na Byeong-mo into Choi Sung Group and expanded his influence by leading cooperation between Taeha Group and Choi Sung Group in front of the presidents. In particular, even when Kang Jae-kyung (Jeon Hye-jin) was in crisis under Na Byeong-mo's pressure, Naeun-se stayed by her side, establishing himself as a pillar of a power alliance beyond simple family ties.

However, Naeun-se's true self was hidden beneath the composure and distance he maintained. Even during the business promotion process with Taeha Group, he maintained an attitude of prioritizing profit and results over emotions, observing the movements of surrounding characters to design the board in a direction favorable to himself. This signified the birth of a new power-oriented character possessing cold judgment and strategy, rather than a simple character of desire often depicted in chaebol succession competitions.

Above all, the ending of episode 10 completely overturned the viewers' existing perception of the character Naeun-se. In a situation where Kang Jae-kyung was suspected as the mastermind behind the death of Chairman Kang Yong-ho (Son Hyun-joo), it was revealed that the person who visited the hospital room was Naeun-se, dressed in the same clothes as Kang Jae-kyung. The subsequent scene, where Naeun-se removes Kang Yong-ho's ventilator and leaves the hospital as if nothing happened, was a shocking twist that reshaped the entire narrative of the drama.

This scene was not merely the reveal of a culprit, but a moment where Naeun-se's long-hidden desire and will for power exploded. It moved away from the superficial question of 'who will become the successor' and heightened the tension of the succession war by reminding viewers of the work's fundamental theme: 'how far can one go for the sake of power?'

Lee Seo-an persuaded the audience with stable acting skills for this complex character. While maintaining a calm and rational appearance on the surface, he expressed Naeun-se's duality through cold glares and subtle emotional shifts. Rather than exaggerated villainous acting, he established himself as the central axis of the drama by creating even stronger anxiety and tension through restrained expression.

In particular, Naeun-se is differentiated in that he is not the typical successor repeatedly appearing in existing chaebol dramas, but a character trying to prove his own existence. His constant calculation and selection even within the fence of family shows the raw face of the chaebol power structure where 'bloodline' and 'ability' collide.

With only 2 episodes remaining until the finale, attention is focused on why Naeun-se chose the death of Chairman Kang Yong-ho and what changes his final goal will bring to the succession structure of Choi Sung Group. The variable named Naeun-se, created by Lee Seo-an, is expected to be the most powerful key in determining the final conclusion of 'Reborn Rookie.'
