Director: Kim Na Young, Yoon Ji Hoon
A career-ending injury, a psychiatric gadget that promises a clean slate, and a false memory that refuses to stay false — Bad Memory Eraser turns heartbreak into an unlikely comedy about second chances.
What is Bad Memory Eraser about?
Lee Goon was on track to be a tennis star until one injury ended it overnight, leaving him adrift and bitter. Chasing any way back to his old confidence, he starts using an experimental device nicknamed the memory eraser, designed to soften or rewrite painful recollections. The tool works, but not cleanly: it plants a memory that never happened, convincing Goon that his psychiatrist, Kyung Joo Yeon, was his first love. What should be a harmless glitch spirals into something messier, as Goon can no longer tell which feelings are real and which were manufactured by the machine. Joo Yeon, meanwhile, has to treat a patient who is quietly falling for a version of her that exists only in his altered memory. The show plays the setup for both laughs and genuine ache, following the two of them toward a romance that starts as a mistake and slowly stops being one.
Cast & crew
Kim Jae-joong plays Lee Goon with a wounded charm that keeps the character sympathetic even when his memory-fueled confusion gets him into trouble, and Jin Se-yeon gives Kyung Joo Yeon a grounded skepticism that balances the show's sillier stretches. Lee Jong-won, Yang Hye-ji, and Lee Jun-hyeok round out a supporting cast that keeps the tone light without undercutting the central couple's stakes, under the joint direction of Kim Na Young and Yoon Ji Hoon.
Context & significance
Bad Memory Eraser leans on a familiar Korean drama device — a piece of speculative technology that exists purely to complicate the leads' feelings — and uses it to ask a fairly ordinary question: how much of attraction is chosen versus imposed. Released in 2024 and running a compact 60 minutes per episode, it sits closer to a rom-com than a science-fiction premise would suggest, prioritizing chemistry over mechanics.
Where & how to watch
Bad Memory Eraser is available on K-Time with Persian dubbing and Persian subtitles, so the show's comic timing and quieter moments both land for Farsi-speaking audiences. The synopsis and details on this page are free to read for anyone; watching the full episodes requires logging into a K-Time account, and the platform itself is built with a Farsi-first interface for the diaspora.
