Bad-Memory Eraser: Episodes 5-6

As our amnesiac hero begins to regain his footing, his brilliant mind springs into action, but a series of crises throws his psychiatrist, Joo-yeon, into turmoil. Love, it turns out, is far more complex than any diagnosis, and the game of the heart proves to be the toughest one yet.

Joo-yeon bluffs her way out of a trespassing incident with a half-baked excuse, but soon finds herself tangled deeper in Gun's unpredictable life. Since he keeps sneaking out of the hospital unaccompanied, Joo-yeon takes it upon herself to follow him — leading her to a racetrack where Gun, trying to woo a potential investor for his fledgling agency, improvises a plan. He pulls Joo-yeon into his scheme, falsely claiming she's the team's doctor, and the two pull off a stunning victory, predicting the winning horse and securing the investor’s interest.

Meanwhile, Joo-yeon plans a surprise for her old flame, Teo, who recently returned from Italy. She goes all out, decorating a hospital meeting room with balloons and candles, only to overhear Teo flirting with a junior researcher in a stairwell. Heartbroken, she hurriedly extinguishes the candles, trying to hide her disappointment before he sees. Gun walks in on the aftermath, and when Joo-yeon refuses to cry, he accuses her of deceiving herself, hiding her vulnerability behind a facade of toughness. Stung by his words, she snaps, telling him to back off.

Later, Joo-yeon is found by Shin, crouching by the hospital curb, struggling to hold back her tears. He takes her home and buys her hot chocolate, which she offers to share. Shin resists at first, but soon gives in, only to find himself lying awake that night, clutching his chest and grinning like a lovesick teenager.

But while Shin revels in his newfound feelings, he’s haunted by his past with Sae-yan, a woman not easily forgotten. After confronting him about a lost bracelet, she swiftly puts him in his place, reminding him of their turbulent history. In a flashback to their high school days, Sae-yan had dramatically kissed and slapped Shin, declaring, "I'm the one who’s dumping you!" Now, as she ties the bracelet back on, it’s clear she’s hoping for something more — just as Gun yearns to reunite with his mysterious first love. But is Sae-yan truly the one he’s been searching for, or is there more to the story?

Meanwhile, Joo-yeon faces an uphill battle at the hospital. The director is steering the research project away from psychiatry and into neuroscience, and Teo is secretly conducting tests on Gun. When Joo-yeon discovers Teo’s deception, she confronts him, dumping the trash from his desk back onto it in defiance. Exhausted and drenched from the rain, she shows up at Gun’s door, announcing she’s accepting the role of his team doctor — and boldly asks to stay at his place for three months.

Gun, however, isn’t so quick to let her in. Determined to distance himself from his old feelings, he refuses. But Joo-yeon challenges him: if she can convince Shi-on to stay with Gun’s agency and continue physiotherapy, Gun must hire her. Despite her lack of tennis knowledge, Joo-yeon throws herself into learning the sport, with Shin eagerly offering to help. As they practice together, Shin’s affection for her only grows, his heart fluttering with every swing of the racket, even when her ponytail smacks him in the face.

But danger lurks as Joo-yeon senses someone following her. Luckily, Gun intervenes, taking down the stalker — Teo, who claims he only wanted to apologize. His intentions, however, sow doubt in Gun’s mind. Is Joo-yeon truly his first love? Can he even remember how they met?

As the pieces of the puzzle start to fall into place, the tension between Gun and Joo-yeon builds. When Shin unexpectedly shows up at Gun’s doorstep, Gun makes his boldest declaration yet: "That’s right, she’s my first love." But is the truth really that simple, or is their story only just beginning?

DramaZen's Opinion

Alright, let’s talk about Bad-Memory Eraser Episode 5, and why it’s suddenly making us sympathize with Shin and Ju-yeon. Hear me out—now that we’ve seen things from their point of view, they’re not quite the villains we thought. The drama’s been hinting at this since Episode 1, showing how self-pity can spiral into misunderstandings. While Gun’s feelings of abandonment by his family are valid (they’ve done little to prove otherwise), things aren’t as black and white as they seem.

Take Shin, for instance. He might not even realize that Sae-yan was Gun’s first love. The car scene that looked so damning? It wasn’t a secret tryst—it was a breakup. Ju-yeon, on the other hand, never lied about her relationship with Tae-oh. From her perspective, distancing herself from Gun makes sense—he’s crossed boundaries repeatedly, holding her against her will. Plus, as his psychiatrist, Ju-yeon’s professionalism is on the line, especially with her trial in jeopardy thanks to her cheating ex. Her career and heart are in a tangled mess, yet now that she’s single, you can bet the romance is about to heat up. With Ju-yeon’s feelings for Gun starting to show, Shin crushing on her, and Sae-yan’s interest in Gun, we’re heading straight into the love square drama we were promised.

And wait a minute, maybe Gun didn’t throw himself into the river to drown after all. What if it was Shin who tossed Gun’s medal in during a heated argument, and Gun fell in trying to retrieve it? Things are definitely getting more layered than we thought.

But let’s not forget about Tae-oh. Is he onto Ju-yeon’s first love lie? We’re dying for Gun to learn the truth, but Tae-oh having that kind of leverage. No thanks. Tae-oh’s no saint—he led Ju-yeon on for months, all while playing it cool. His story about the “misunderstanding” coming up in Episode 6 feels off too. If he always intended to date her, why did he give another girl a gold necklace and Ju-yeon a basic keyring like the rest of the staff? Not exactly romantic hero material.

Now, let’s talk about Ju-yeon. She’s been rude to almost everyone—Gun, Sae-yan—but they keep bending over backward for her. When Shin does it, it makes sense; they’ve shared a lot of history. But with everyone else? Not so much. We get it—Ju-yeon’s the “grumpy protector,” but it’s becoming clear that Shin, not Gun, has been her source of light all along. If the writers are still planning to make Gun and Ju-yeon endgame, they better have a good explanation, or we’re in for a rushed and messy conclusion.
