Did you know that Bad Memory Eraser has already become one of the most talked-about K-dramas of 2025? The show, starring Kim Jaejoong and Jin Se-yeon, premiered on MBN and instantly captured the attention of fans both in Korea and abroad. With its intriguing concept of erasing painful memories and the tangled romance that follows, the drama promises a rollercoaster of emotions and unexpected twists. Let’s dive into the first episode’s plot, the critical and fan reviews, and why international viewers are finding it so relatable.

Episode 1 Plot Summary: When the Past Is Deleted

The story opens with Lee Gun (Kim Jaejoong), a once-promising tennis player whose career and confidence were shattered by a traumatic incident. Desperate to move on, he volunteers for an experimental surgery known as the 'bad memory eraser.' The procedure wipes away his most painful memories, giving him a fresh start—but at a cost. When he wakes up, Lee Gun mistakenly believes that Kyung Ju-yeon (Jin Se-yeon), a neurosurgeon involved in the experiment, is his childhood first love. This sets off a chain of awkward, touching, and sometimes comedic moments as Gun navigates his new reality, and Ju-yeon struggles with guilt and confusion over her unexpected role in his life.
The episode balances emotional depth with light-hearted scenes, introducing supporting characters like Gun’s quirky family and Ju-yeon’s colleagues, who add both humor and tension. By the end of the first episode, viewers are left questioning the ethics of memory manipulation and rooting for the leads as they stumble through their new relationship.

Cast and Chemistry: The Heart of the Show

Kim Jaejoong’s return to drama after seven years is a major draw. His portrayal of Lee Gun is both vulnerable and charismatic, making it easy for viewers to empathize with his journey. Jin Se-yeon shines as Kyung Ju-yeon, skillfully conveying the internal conflict of a doctor who never expected to become someone’s fabricated first love. The chemistry between the leads is already being praised on social media and in reviews, with many calling it 'refreshing' and 'unexpectedly sweet.'
Supporting actors like Lee Jong-won and Yang Hye-ji round out the cast, each bringing their own flair to the story and keeping the energy high. The ensemble’s dynamic is one of the reasons the first episode feels so lively and engaging.
