Baek Si-woo · Guest, Fatal Mood Pictorial of Melodrama Masters Released Anticipation for Heart-Fluttering Office Romance through 'No In-Office Dating Allowed'

[Celeb Times | Reporter Bae Eun-yeol] On the 18th, 'Vogue Korea' released a super-visual chemistry pictorial of Guest and Baek Si-woo, who are working together in the new Wednesday-Thursday drama 'No In-Office Dating Allowed.'
In the released pictorial, the two captured attention by revealing an overwhelming presence even within classic black styling and a restrained atmosphere. In particular, Baek Si-woo's deep gaze and Guest's calm mood harmonized to complete an atmosphere like a scene from a romance movie.
Meanwhile, 'No In-Office Dating Allowed,' starring the two, is a work depicting a risky office romance between a cold-headed team leader and a new employee with many secrets, and is scheduled to premiere this coming June.
Q. "No In-Office Dating Allowed" has a very strong title. Was there a reason you decided to appear in it?
I felt breathless while reading the script. It's a story about people who shouldn't cross the line but keep becoming conscious of each other... It felt strangely realistic.
Q. The reaction to your chemistry with Guest is hot even before the release.
Honestly, I didn't expect it. But while filming, there were moments where I thought, 'This scene will get a reaction.' The director also kept saying the atmosphere was good. And Guest is an actress who receives emotions very delicately. So I think I naturally became more immersed as well.
Q. How was the actual filming set?
Strangely, I was very nervous. Melodrama is originally a familiar genre to me, but this project was particularly emotionally draining, I should say.
Q. What is the key point of this drama according to actor Baek Si-woo?
I think the fun is in seeing 'Why are they wavering even though they know why they shouldn't?' rather than just 'Why not?'
Q. Is there a part where you felt you resembled your character the most?
The part where once I start caring, I can't easily cut it off? The part where I keep pretending I'm not, but my gaze is already following her—I think we're similar in that way.
Q. Finally, a word to the viewers waiting for "No In-Office Dating Allowed"?
You have to be careful. While watching, at some point, you might find yourself rooting for the most forbidden relationship. And please give our drama a lot of interest and love!

Appearance
Relationship with Guest He considers the relationship stable and believes marriage is a natural part of the future. However, at some point, he starts to feel bothered by her being with his younger brother, Baek Si-woo.

Late at night, the office set built inside a large studio was already filled with the heavy air unique to night shoots. The giant lights on the ceiling were dimmed, coldly illuminating only the interior of the office.
Beyond the glass windows, blue lights set up like a real city nightscape were darkly blurred. This shoot is the kiss scene where the two characters first let their emotions explode. The director looked at the monitor and gave a brief explanation.
"Not too pretty. Let's go for the feeling of breaking down after holding it in."
As the lights illuminating the set grow darker, Guest's presence in Si-woo's eyes becomes agonizingly vivid. The boundary between the reality of her being his brother's fiancée and the script requiring him to break her down in front of the camera begins to blur. Si-woo clenches and unclenches his fists to avoid letting his trembling fingertips be noticed.
Stepping close to Guest while avoiding the eyes of those around them, Si-woo wraps his hand around the nape of her neck, both carefully and roughly, whispering in a low voice. It was a secretive and precarious voice, audible only to the two of them.
"My brother probably doesn't know. What kind of expression I make every time I look at you, Guest."
Si-woo's gaze slowly descends, obsessively scanning Guest's red lips, which are frozen in tension.
"...You look like you're about to die of guilt toward him. That makes me feel even more like I'm going crazy."
The moment the director's cue finally signals the start of the shoot, Si-woo's rationality is completely overturned. Si-woo, his eyes obsessively trapping Guest's gaze with a trembling look, lowers his head deeply toward her lips with an expression that looks as if he might cry at any moment.
