Episode 5 Key Summary
Story Flow
GF Solution becomes new prey in the succession fight
In Episode 5, Jae-kyung and Jae-sung clash head-on over the acquisition of GF Solution. On the surface, it looks like a corporate takeover, but underneath it is a pride war tied to the succession structure of Choi Sung Group. Depending on who delivers the bigger achievement, the board and internal factions may shift their attention. Jun-hyun sees that exact weak point. He is less interested in GF Solution itself than in the siblings’ greed. He knows they both want to defeat each other, so he intentionally fuels the competition and makes the board larger.
Jun-hyun drives the price up through sibling rivalry
The official Episode 5 description explains that Jun-hyun provokes Jae-kyung and Jae-sung’s competitive instincts, pushes up GF Solution’s value, and plans to siphon money through the gap. Jun-hyun’s strength here is not simple fraud or luck. As Chairman Kang Yong-ho, he has spent his life reading people’s desires and weaknesses. Jae-kyung is calculating, while Jae-sung is emotional. Jun-hyun uses that difference. He touches one side’s need to win and the other side’s fear of losing. In the end, the GF Solution acquisition is not a test of who can buy a company; it becomes a test of who is easier to manipulate.
Manager Park becomes clumsy but decisive help
Manager Park is the person who fell for Jun-hyun’s lie and believed him to be Chairman Kang’s youngest son. But in Episode 5, his role is not limited to comedy. The official VOD clip list includes a scene where Manager Park moves money on Jun-hyun’s behalf while Jun-hyun is being tailed. Manager Park’s advantage is not perfection but unpredictability. Jae-kyung and Jae-sung do not treat him as a major variable, but Jun-hyun uses exactly that blind spot. After Chairman Kang comes down into the body of a low-ranking rookie, the biggest weapon he gains is not a grand title but the movement of ordinary people the upper ranks ignore.
Bang-geul holds both emotion and reality
Bang-geul is the person who adjusts the pace beside Jun-hyun’s operation. If Jun-hyun sees the company through Chairman Kang Yong-ho’s eyes, Bang-geul senses the feelings and realities of the people who are actually inside the workplace. That is why their cooperation becomes increasingly important. In Episode 5, Bang-geul watches Jun-hyun’s recklessness, but she also begins to understand what kind of board he is building. As the GF Solution battle grows, she stops being a simple companion and becomes a partner who helps turn Jun-hyun’s strategy into reality.
Lee Sang-jae finally sees traces of Chairman Kang
In the Episode 5 pre-release, Jun-hyun claims that he is Kang Yong-ho, and Lee Sang-jae falls into confusion. Jun-hyun has the young face of Hwang Jun-hyun, but his speech, memories, and way of judging situations resemble Chairman Kang too closely. The official VOD clips also introduce a scene where Lee Sang-jae accepts Jun-hyun’s identity and becomes overwhelmed. This is a major change. If Jun-hyun were alone, every operation would remain dangerous. But if Sang-jae joins him, the story changes. Sang-jae is the loyal aide Kang Yong-ho once trusted most, and he knows the inner structure of Choi Sung Group better than anyone. Episode 5 is also the episode where Chairman Kang begins recovering his people.
Jae-kyung’s scouting offer and Jun-hyun’s bold demand
The official clip list for Episode 5 includes a scene where Jae-kyung lowers her head to scout Jun-hyun, and another scene where Jun-hyun helps her win through his strategy and then makes a bold demand. This means Jae-kyung no longer sees Jun-hyun as an ordinary rookie. From her point of view, Jun-hyun is dangerous but tempting: a strategist who can strike Jae-sung from behind, and at the same time a variable she may not be able to control. Jun-hyun uses that ambiguous position. He becomes someone who is not fully an ally, yet cannot be easily discarded, and he shakes the balance between Jae-kyung and Jae-sung.
The airplane ending moves the next board overseas
The official Episode 5 VOD clips reveal an ending where Lee Jun-young’s group boards a plane and heads somewhere new. The Episode 6 preview then explains that Jun-hyun, Bang-geul, and Manager Park leave for Yulivia to design a new board and begin an operation to seize lithium business rights that Taeha Group chairman Byung-mo has worked on for a long time. In other words, the Episode 5 ending is not the end of the GF Solution acquisition story; it is the entrance to the next war. As the domestic succession fight expands into overseas lithium rights, Chairman Kang’s second life moves onto a much larger board.
Character Viewing Points
| Character | What to watch in Episode 5 |
|---|---|
| Hwang Jun-hyun / Kang Yong-ho | He uses the GF Solution acquisition to explode Jae-kyung and Jae-sung’s rivalry. His body is young, but his way of reading the board is still Chairman Kang’s. |
| Kang Bang-geul | She supplements Jun-hyun’s reckless plan with a sense of reality and becomes more than the youngest daughter; she turns into a partner in the operation. |
| Kang Jae-kyung | She competes with Jae-sung over GF Solution and recognizes Jun-hyun’s ability, but she still does not fully understand his identity or intent. |
| Kang Jae-sung | He jumps into the board because he cannot bear losing to Jae-kyung. His emotional response is used by Jun-hyun’s strategy. |
| Manager Park | He looks like a comic helper, but he plays a decisive role in the tailing and money-diversion operation. |
| Lee Sang-jae | He suspects Jun-hyun’s identity and begins recognizing traces of Kang Yong-ho. Whether he joins Jun-hyun may change the later power balance. |
The meaning of the preview line: “Still don’t know who I am?”
The Episode 5 preview title, “Still don’t know who I am?”, is not merely a line that reveals identity. It shows the situation itself: Kang Yong-ho, inside Hwang Jun-hyun’s body, must prove who he is. No matter how accurately he judges situations, and no matter how many memories only Kang Yong-ho could know, people first see the face of a young rookie and doubt him.
That is why Episode 5 is closer to an episode about proving identity than simply exposing it. Jun-hyun cannot merely say that he is Kang Yong-ho. He must prove his existence through judgments only Kang Yong-ho could make, relationships only Kang Yong-ho could know, and boards only Kang Yong-ho could design.
Ending Interpretation
The meaning of Episode 5’s ending is clear. Jun-hyun is no longer moving only inside Choi Sung Group. After shaking Jae-kyung and Jae-sung through the GF Solution battle, the next board expands into Yulivia’s lithium business rights. This means Chairman Kang’s counterattack will not remain a family lesson or an internal revenge story.
Another important shift is Lee Sang-jae. If Sang-jae starts accepting Jun-hyun’s identity, Jun-hyun has recovered part of Kang Yong-ho’s old network. Manager Park and Bang-geul are helpers from the present, while Sang-jae is a helper connected to the memory of past power. When those two axes meet, Jun-hyun’s operations can become more precise.
But the risk grows as well. Jae-kyung wants Jun-hyun’s ability, and Jae-sung continues to be dragged around by the board Jun-hyun built. The more Jun-hyun’s presence grows, the more suspicion around his identity grows, and the higher the possibility that the name Kang Yong-ho will surface again.

Final Thoughts
Episode 5 moves Chairman Kang’s second life beyond workplace adaptation and into full corporate warfare. The GF Solution acquisition exposes Jae-kyung and Jae-sung’s greed, and Jun-hyun overturns the board by using that greed.
Most importantly, Sang-jae approaching the truth becomes a major turning point for the latter half. The rookie chairman, who had been moving alone, begins gaining his people again. With Bang-geul and Manager Park also moving beside him, the scope of the operation grows wider. Episode 6 is likely to become rougher as the lithium-rights board and Jae-kyung’s chairmanship attempt collide.
