The Premise: Love’s Long-Buried Secrets
“Last Summer” follows childhood friends Baek Do Ha (Lee Jae Wook) and Song Ha Kyung (Choi Sung Eun) as they uncover long-hidden truths about their first love—secrets buried away like Pandora’s box. The drama explores how the innocence of youth intersects with the complexities of adult emotions when the past refuses to stay buried.

The Pandora’s box metaphor suggests that once these truths emerge, they’ll irrevocably change everything these characters thought they knew about their relationship. It’s a premise that promises both nostalgia and tension, tapping into the universal experience of wondering “what if” about past connections.
A Summer Romance Interrupted
The newly released teaser opens with bittersweet nostalgia as Song Ha Kyung reflects, “We met that summer when we were 12.” Sweet childhood memories flash across the screen before Baek Do Ha continues, “And again in our 19th summer. That summer was mine. At least, up until then…”
That haunting qualifier—”up until then”—sets the stage for heartbreak. The teaser skillfully establishes that Baek Do Ha believed he and Song Ha Kyung shared something special during their 19th summer, only to watch that certainty crumble when a third person enters the picture.
Enter the Rival: Kim Gun Woo’s Seo Soo Hyuk
The story takes a dramatic turn with the introduction of Seo Soo Hyuk, played by rising actor Kim Gun Woo. His character boldly tells Song Ha Kyung, “Let’s try dating,” creating immediate tension in what had seemed like a destined romance between childhood friends.
The teaser showcases the growing connection between Song Ha Kyung and Seo Soo Hyuk through intimate moments—spending quality time together, sharing affectionate gestures, and coming dangerously close to a kiss. These scenes are interspersed with shots of Baek Do Ha watching from the sidelines, his discomfort and jealousy building with each stolen glance.
Lee Jae Wook’s Jealous Awakening
Lee Jae Wook’s portrayal of jealousy promises to be a highlight of the drama. The teaser captures the subtle yet powerful shift in Baek Do Ha’s demeanor as he realizes he’s losing his grip on a relationship he took for granted. His growing discomfort evolves into active intervention, suggesting he won’t simply accept defeat.
This character dynamic is particularly compelling because it subverts the typical childhood friends-to-lovers trope. Rather than coasting on shared history, Baek Do Ha must actively fight for Song Ha Kyung’s affection against someone who brings fresh excitement and intentional pursuit.

The Stakes Get Personal
The teaser closes with an ominous declaration: “I have no choice but to do all I can.” This line, delivered with determination, hints that characters will push boundaries and take risks for love. The phrase suggests desperation—a willingness to do whatever it takes, potentially leading to dramatic confrontations and difficult choices.
This intensity elevates “Last Summer” beyond a simple love triangle into a deeper exploration of how far people will go when facing the loss of their first love. The emotional stakes promise authentic tension that keeps viewers invested in the outcome.
Why This Love Triangle Feels Different
What sets “Last Summer” apart from typical love triangle dramas is its foundation in childhood friendship and the mysterious “hidden truth” element. The characters aren’t strangers navigating attraction—they share deep history that complicates every decision. When past secrets emerge, they’ll color every memory and force characters to question everything they believed about their relationships.
The nostalgic summer setting also adds atmospheric appeal, evoking the bittersweet quality of youth slipping away. Summer romances carry inherent tension about endings, making them perfect backdrops for dramatic emotional arcs.
