Last Summer OTT Release Date and Streaming Platform

Last Summer will premiere on Rakuten Viki on November 1, 2025, with two new episodes releasing every Saturday and Sunday. The series will consist of 12 episodes and conclude by December 7, 2025.

Plot: A Tale of Love, Guilt, and Second Chances

At its core, Last Summer explores the bittersweet reunion of two childhood friends, Baek Do-ha (Lee Jae-wook) and Song Ha-kyung (Choi Sung-eun). Once inseparable, their friendship was torn apart by a tragic accident that left Ha-kyung guilt-ridden and Do-ha burdened with a painful secret.

To protect her, Do-ha assumes his twin brother’s identity, living a life built on lies and sacrifice. Years later, fate brings them together again, forcing both to confront the past they’ve tried to bury.

Set against the backdrop of the architecture industry, the series weaves themes of romance, grief, identity crisis, and workplace politics — all framed within the tender warmth of summer memories.

Teaser Breakdown: From Separation to Rekindled Love

The emotional 50-second teaser opens with a heartbreaking scene — both leads dressed in mourning attire. Ha-kyung, filled with anger and grief, declares to Do-ha, “Let’s never see each other again.”

As the teaser transitions, time passes, and the two reunite under unexpected circumstances. Now cohabiting under a contractual agreement, Do-ha finds himself drawn once again to Ha-kyung’s familiar habits, reigniting the affection he once tried to suppress.

The teaser skillfully captures the duality of love and pain, hinting at a layered narrative filled with unresolved emotions and heartfelt nostalgia.
