Brother’s Rival, My Secret Lover

Episode 1

Cha Eunhye arrives in the city and steps straight into a world that isn't hers. At the ice rink, her older brother Cha Injun, the hockey captain, is locked in a fierce rivalry with Bak Seonghun — the rich, handsome player everyone can't stop watching. Injun's warning is blunt: stay away from men like Seonghun, a guy with a bad reputation and no shortage of female attention.

Eunhye insists she hasn't even met him, so what's the risk? But the city has its own plans, and so does Seonghun. She's about to learn that promising to avoid someone is very different from actually managing it.

Episode 2

Eunhye is finding her footing at school, but Seonghun keeps surfacing in her orbit. When a senior starts needling her about newbie etiquette, he steps in — not exactly a rescue, more like a claim. He makes it clear he doesn't like anyone bothering her, because if anyone gets to, it's him.

Meanwhile, Eunhye fends off other admirers with cool indifference, insisting she has no interest in dating. She's polite, distant, and completely unmoved by the attention swirling around her. That calm is exactly what catches Seonghun's eye. Most people chase him; she barely looks his way — and he notices.

Episode 3

Injun's protective streak goes into overdrive. He warns Seonghun directly to stay away from Eunhye, threatening him if he keeps circling her. But Eunhye has a request of her own: she wants Injun to hide the fact that she's his sister. She doesn't want special treatment — she wants to earn recognition on her own, without the captain's shadow hanging over her.

Injun agrees, and for her birthday he gives her a dress, one of the nicest gifts he can find. It's a warm moment between siblings. Yet Eunhye's world keeps pulling tighter around Seonghun, and secrets like this rarely stay buried for long.

Episode 4

A run-in turns intimate fast. Eunhye insists she has no feelings for Seonghun, but he isn't buying it — her racing heart gives her away, and he points it out with a smirk. She fires back that she's not like the other girls who chase him, that she doesn't want anything from him.

He's clearly enjoying her resistance, the way she refuses to melt like everyone else. Eunhye keeps telling herself the same thing: he's her brother's rival, a player who toys with women. But telling herself and believing it are two very different battles, and she's losing ground.

Episode 5

Injun catches Eunhye near Seonghun's room and demands answers. She scrambles for an excuse, but Injun's patience is gone. He tells her plainly that Seonghun is his sworn enemy, a complete piece of trash, and she is not to go anywhere near him — not even once.

Eunhye promises she hasn't even run into him. Then Injun softens and gives her a birthday gift: a dress, a symbol of how much he treasures her. She teases that he still treats her like a child to protect. But alone, her thoughts keep drifting back to Seonghun — and she has to force herself to stop.

Episode 6

Eunhye wears her new dress and immediately draws the wrong kind of attention. Jealous classmates corner her, sneering about a country girl in an expensive outfit, accusing her of wearing a knockoff and demanding to know who could possibly gift her something so pricey.

Their cruelty escalates — they mock her, crowd her, and ruin the dress on purpose, then pretend to offer to "clean" it. It's a sharp reminder that Eunhye's new life comes with people determined to cut her down. Just as it turns ugly, a familiar presence arrives — and the mood shifts entirely.

Episode 7

The party spirals. When the harassment over the dress crosses a line, Seonghun steps in, and Eunhye is horrified that her brother might see any of it. Seonghun's father, Min Yeongseo, appears in the middle of the chaos, and the tension turns into something bigger than a school spat.

Seonghun makes a hard threat: anyone who uploads the video online will face legal action. He deletes everything, shielding Eunhye from a scandal that could reach Injun. She's rattled — grateful, wary, and increasingly tangled in a secret she can't explain to anyone.

Episode 8

Seonghun keeps showing up exactly when Eunhye is most vulnerable. After she's soaked and freezing, he makes sure she's taken care of, then needles her about gratitude — suggesting words aren't enough and he deserves something more.

Eunhye pushes back, insisting she isn't someone who can be swayed so easily, and that the only person she cares about is Injun. But then she spots her necklace in his possession, and the air changes. He twists it into a taunt about her having a crush on someone. She's cornered, flustered, and running out of ways to pretend she feels nothing.

Episode 9

Seonghun corners Eunhye with an ultimatum wrapped in a smile. He wants her to keep their encounters secret, and he hints she has no real choice — if she tells anyone, it only hurts her, since she doesn't want Injun knowing she's been near him.

She calls him childish and ridiculous, refusing to play along. Yet the trap is real: any exposure risks her brother's trust and her fresh start. Before she can untangle it, someone knocks, and the conversation is cut short. The secret only grows heavier.

Episode 10

The pressure peaks. Eunhye is desperate to get Seonghun out of sight before anyone sees them together, practically begging him to leave. He drags his feet, bargaining — coffee with him, a promise — before he'll finally go.

She agrees just to make him disappear, her voice tight with panic. It's a small surrender, but it's a surrender, and he knows it. The episode ends on that uneasy deal: Eunhye buying herself a moment of safety by handing Seonghun exactly the opening he wanted.

Eunhye's story only gets messier from here — start watching and see how long she can keep her brother's rival at arm's length.
