[Exclusive] 'Today and Tomorrow' Reunite... Yoon Haru to Star in Director Seo Naeil's Next Project

Yoon Oneul and Seo Naeil are childhood friends who grew up next door to each other since birth. They attended the same kindergarten, elementary, middle, and high schools, and even the same university. Because their names were 'Oneul' (Today) and 'Naeil' (Tomorrow), people around them naturally grouped them together as 'Today and Tomorrow' since they were young. Having spent so much time together, there is almost nothing they don't know about each other. They know everything from each other's first loves to their most hidden embarrassing moments, and even the look on each other's faces on a day they failed an exam. They can instantly tell what verbal habits come out when the other is angry or where their eyes dart when they are lying.
Thus, they are closer than anyone, but at the same time, they are sick of each other. They pick fights over trivial things whenever they meet and don't hesitate to expose each other's dark pasts. While they claim they wouldn't mind never seeing each other again, they are always the first to run to the other's side when something happens.
The first time these two were completely separated since birth was after university graduation. As they began to walk different paths, they thought they had finally escaped the tiresome 'Today and Tomorrow.' In their youth, they were together because they had been by each other's side since birth, but now it was different. After time passed, Seo Naeil personally chose Yoon Oneul as the lead among countless actors while preparing for her next project.
The character Yoon Oneul will play is a serial killer who has already murdered nineteen people. Not yet caught by the police, he considers his crimes a 'work of art' and is searching for his twentieth victim to complete his next masterpiece.
Yoon Oneul doesn't know yet. Why Seo Naeil chose him specifically, despite the many actors available. Why Seo Naeil, who has known him better than anyone for so long, assigned him the role of a 'serial killer'...

"Live for a better tomorrow than today." "Live today and each day preciously."
They were good meanings. At least, that's what their parents must have thought.
Yoon Oneul and Seo Naeil. Born to long-time friends and raised as next-door neighbors, they were rivals of 30 years. From daycare to elementary, middle, and high school, and even the Korea National University of Arts, the two were always together.
"Where did Today go?" "He's with Tomorrow." "If there's no Today, isn't there no Tomorrow?"
People arbitrarily grouped them together as 'Today and Tomorrow.' Yoon Oneul hated Seo Naeil. More accurately, he was sick of his life always being treated as a package deal with her.
After graduating from university, the two were separated for the first time. Yoon Oneul became an actor under the stage name 'Yoon Haru,' and he thought 'Today and Tomorrow' was finally over.
However, the director of his next project was Seo Naeil.
The role Yoon Haru took on was a serial killer who had already murdered nineteen people. A sociopath wearing the mask of a romanticist, he called his crimes 'works of art' and wandered in search of his twentieth victim.
Yoon Haru doesn't know yet. Why, out of all the actors, Seo Naeil chose him.
Seongsu-dong, Seoul. A meeting room on the 4th floor of the HJ Entertainment building. At 2:00 PM, as the late autumn sunlight poured in through the window at an angle, Yoon Oneul sat buried deep in his chair, tapping a copy of the script his manager had handed him.
The moment he saw the director's name written on the cover of the script, the corners of his mouth twitched.
Ah, seriously. Of all people, it's her? Seo Naeil?
He leaned his head back, pressing his fingers to his forehead. The fluorescent lights on the ceiling stung his eyes. He glanced toward his manager, narrowing his eyes as if to confirm this wasn't a joke.
Hyung, is this for real? What if I say I don't want to do it?
Manager Park Seong-ho puts down his tablet and says,
Haru, you're not at a level where you can just say no. The production company has already released the press materials, and a pre-meeting with Director Seo is already scheduled.
Yoon Haru flips through the script irritably.
