In the story of Last Summer, the past between Song Ha-gyeong, Baek Do-ha, and his twin brother Baek Do-yeong is one filled with love, guilt, and heartbreak. Years ago, Ha-gyeong found herself caught between two hearts. Though she was close to both brothers, her heart quietly leaned toward Do-ha. One evening, she gathered the courage to confess her feelings to Do-yeong—not because she loved him, but because she wanted to be honest about her heart belonging to his brother. It was a confession made out of truth, but it tore their bond apart.
Moments later, Do-yeong witnessed what he feared most — Ha-gyeong and Do-ha sharing their first kiss. The scene was tender but devastating, not only for Do-yeong but also for Ha-gyeong, who realized too late that her honesty had wounded the people she cared for most. Unable to face them, Do-yeong packed his things and left the Peanut House, their childhood haven. His silent departure changed everything. From that day, the laughter faded, the memories became painful, and Ha-gyeong was left with a guilt that would haunt her for years.
Ha-gyeong carried the weight of that summer like a scar that never healed. She blamed herself for Do-yeong’s disappearance and couldn’t bring herself to look at Do-ha the same way again. Even though he was the one she loved, every memory of him—every smile, every shared moment—was tied to the pain of losing his twin. The sweetness of their first kiss turned bitter with regret. The place once filled with warmth became a reminder of what her love had cost.
For Do-ha, the situation was no less painful. He never meant to hurt his brother, yet his heart couldn’t deny Ha-gyeong. He lived in the shadow of that guilt, watching her withdraw, knowing that her pain was partly his doing. The once vibrant connection between them faded into strained silence, both trapped by memories they couldn’t erase.
Two years later, Ha-gyeong learned the truth that shattered her world — Baek Do-yeong had died. The revelation came too late, wrapped in letters that she believed were written by Do-yeong himself. Those letters had brought her comfort through lonely nights, a fragile hope that he was still alive somewhere. But the cruel truth emerged: it was Do-ha who had written them, pretending to be his dead brother to spare her from grief.
For Ha-gyeong, this was the ultimate betrayal. The man she once loved had turned her memories into lies. Every word of comfort became poison. She began to hate Do-ha not only for his deception but for reviving a past she desperately wanted to forget. The guilt she felt for Do-yeong’s death deepened, and her anger toward Do-ha became the only thing holding her together.
Now, even when she sees Do-ha, the sight of him reminds her of everything she lost — the love that could have been, the brother who’s gone, and the innocence that vanished one tragic summer.
A Love That Can’t Be Forgotten
Last Summer paints a heartbreakingly human portrait of love tangled in guilt and loss. The story of Ha-gyeong, Do-ha, and Do-yeong isn’t just about romance — it’s about the wounds we carry from choices we can’t undo. For Ha-gyeong, every memory is both precious and painful, every glance at Do-ha a reminder of the brother who’s no longer there.
As the truth unfolds, the question remains: can Ha-gyeong ever forgive Do-ha, or will the shadow of that summer keep them apart forever?
