Explosive New Teaser for “Last Summer”: Lee Jae Wook, Choi Sung Eun, and a Childhood Mystery!
Get ready for a summer that’s anything but relaxing! KBS 2TV’s highly anticipated romance drama, “Last Summer,” has just unveiled a gripping highlight teaser, promising a deep dive into the messy, passionate, and complicated relationship between a pair of lifelong friends.
“Last Summer” explores the tumultuous connection between Baek Do Ha (Lee Jae Wook) and Song Ha Kyung (Choi Sung Eun) as they confront a long-buried secret about their first love.
99 Wars, 99 Peace Treaties, and a Duplex at Stake
The teaser immediately transports us to the pivotal summer when Do Ha and Ha Kyung first met as 12-year-olds in their shared duplex. Right from the start, Ha Kyung’s strong-willed nature shines through, marked by a hurled pencil and a squirt of ketchup—a perfect prelude to the next 15 years, which saw their relationship swing wildly between 99 “wars” and 99 “peace treaties.”
The tone shifts dramatically as Do Ha’s narration reveals the depth of their unresolved conflict: “I didn’t know back then that our war would last this long.”
Tragedy, Betrayal, and the Chilling Reunion

The teaser darkens as we see Ha Kyung in mourning clothes, bitterly telling Do Ha to “never to see her again.” Years later, their fraught reunion only hints at the heartbreak that tore them apart. Ha Kyung’s cold remark, “Looks like my summer’s going to be just as unlucky this year,” suggests a past trauma that turned their once-warm friendship icy.
The source of her enduring bitterness is finally revealed as she tries to sell the duplex, only for Do Ha to claim ownership. Their dispute escalates into a lawsuit—a cruel twist for two people who shared a childhood. When Do Ha tries to recall their sweet memories, Ha Kyung furiously warns him not to “force nostalgia” on her.
The Twin Secret and a Budding Love Triangle

Ha Kyung’s true anger stems from Baek Do Young (also played by Lee Jae Wook), Do Ha’s twin brother who shared those formative childhood summers. The painful past involving Do Young is what keeps Ha Kyung emotionally distant, even as she’s forced into an uneasy cohabitation with Do Ha.
Adding even more tension, Do Ha’s lawyer, Seo Soo Hyuk (Kim Gun Woo), who meets Ha Kyung as the plaintiff in the lawsuit, quickly develops an interest in her. His bold declaration, “Let’s date,” sets the stage for a compelling love triangle, pitting the childhood friend (Do Ha) against the new admirer (Soo Hyuk) for Ha Kyung’s heart.
What hidden truth about their first love connects Do Ha, Do Young, and Ha Kyung, and will the lawsuit finally reveal what tore them apart? Get ready to find out!
