You know that feeling when a Kdrama poster drops and suddenly you’re emotionally invested in a show you haven’t even watched yet? Yeah. That just happened.
The newly released posters for The First Night With the Duke are out, and wow, Seohyun dramas really said, “Let’s break the internet today.”
From Hoodie Girl to Joseon Beauty, What a Transformation

One of the posters shows Seohyun as K, a regular college student. K is seen wearing glasses and a hoodie, reading a web novel with an expressionless face that perfectly reflects the monotony of her repetitive daily life.
She looks like every one of us at 2 a.m. scrolling through Wattpad or Webtoon, whispering “just one more chapter.”

Then BAM. The next poster is a total glow-up moment.
We see her as Cha Sun Chaek, dressed in a breathtaking hanbok, with this subtle, mysterious smile. Her entire aura shifts. It’s giving “main character energy,” and we are living for it.
Seohyun Is Owning Both Worlds, and We’re Here for It
Seohyun nails both roles, quiet hoodie-wearing reader and poised noblewoman. The contrast is striking: “Introvert” vs. “I run this kingdom.” These Kdrama posters hint at romance, identity crises, and thrilling chaos. If you love fantasy Kdramas, this one’s definitely for you.
Get Ready, The Countdown Is Officially On
With posters this dramatic, you know the series is about to serve top-tier content.
Whether you’re a longtime fan of Seohyun dramas or just diving into the hype of new Kdrama 2025 releases, this one deserves a front-row spot on your watchlist.
Go check out the posters (and save them for your wallpaper, we won’t judge).
The First Night With the Duke premieres June 11 at 9:50 p.m. KST.
Set your alarms, grab your drama bestie, and let the countdown begin.
Because if the posters are this good… the show’s about to be legendary.
