The Painful Love Triangle Deepens
Last Summer follows childhood friends Baek Do Ha (Lee Jae Wook), a talented architect, and Song Ha Gyeong (Choi Sung Eun), a civil servant yearning to escape her hometown. The drama centers on uncovering the long-buried truth about their first love—but complications arise when third-wheel Seo Su Hyeok (Kim Gun Woo) enters the picture.

What Happened Previously
After a heated argument with Do Ha left Ha Gyeong emotionally raw, she turned to Su Hyeok for comfort. Unlike Do Ha’s complicated hesitations, Su Hyeok proved to be exactly what she needed—a sincere listener who offered thoughtful advice without judgment.
The episode reached its climax when Su Hyeok boldly confessed his feelings and officially asked Ha Gyeong out, fundamentally shifting the dynamics between all three characters. What started as childhood friendship complications has evolved into a full-blown romantic rivalry.
Romance Blossoms Between Ha Gyeong and Su Hyeok
The newly released stills for Episode 7 paint a picture of budding romance that will break Do Ha’s heart. Ha Gyeong and Su Hyeok are seen strolling together through a picturesque hanok village, their gentle smiles radiating new couple energy. The comfortable way they walk side by side suggests their relationship has quickly progressed beyond tentative first dates.
Another preview image shows the pair sharing tea together, with Ha Gyeong’s softened expression and Su Hyeok’s honey-sweet gaze revealing just how far they’ve come since his confession. The chemistry between them is undeniable—but it’s the reaction shot that truly captures the episode’s emotional core.
Do Ha’s Jealous Awakening
While Ha Gyeong and Su Hyeok enjoy their romantic moment, Do Ha witnesses their affection from afar—and his reaction is pure heartbreak. The architect who usually maintains calm composure radiates anxiety and tension, wondering what the pair is doing together alone inside the Peanut House.
The stills show Do Ha with tightly pressed lips, his face a mask of unmistakable jealousy. His usual confidence has evaporated, replaced by the painful realization that he may have missed his chance with the woman he’s loved since childhood.
As Do Ha’s feelings for Ha Gyeong continue deepening, viewers are left wondering: Will he finally confess before it’s too late? Or will his hesitation cost him the love of his life?

The Classic Second Lead Syndrome
For fans following K-drama romance trends, Last Summer delivers quintessential second lead syndrome—the phenomenon where viewers root for the character who won’t end up with the protagonist. Lee Jae Wook’s portrayal of Do Ha’s jealousy showcases why he’s become one of Korea’s most sought-after actors, conveying volumes through subtle facial expressions.
The drama taps into universal experiences: the regret of unspoken feelings, the pain of watching someone you love choose another, and the complicated mess that happens when friendship and romance collide. These themes resonate deeply with audiences, making Last Summer one of the must-watch romantic K-dramas of 2025.
What to Expect in Episode 7
Based on the preview stills, Episode 7 will likely explore:
- Ha Gyeong and Su Hyeok’s relationship development
- Do Ha confronting his feelings and possibly making a move
- The emotional fallout as the love triangle reaches boiling point
- Flashbacks potentially revealing the “truth about their first love”
The drama’s central mystery—what happened during that last summer of their youth—continues building alongside the romantic tension, suggesting the past and present storylines will soon collide.
