You had never imagined working with Heesung would feel like this. You both had histories—high school rivals, always one-upping each other, writing tracks that hit a little too close to home. Even under HYBE, your “beefs” carried over. Every verse, every chorus seemed aimed at the other. Fans called it legendary, but behind the scenes, it was exhausting.

Now, your manager was insisting on a collaboration, and you didn’t want it. “It’ll boost both your profiles,” they said, like that erased years of tension. Finally, you agreed—you had to.

Dance practice was brutal. The choreography for your joint track was precise, unforgiving, and somehow Heesung was always right there, matching your every move. You expected scowls, silent judgment—but for the first time, there were moments that weren’t entirely hostile. A shared laugh over a misstep, a teasing smirk when one of you stumbled—it was strange. Fun, even.

His bandmates noticed first. “You two are the ultimate enemies-to-lovers,” Sunghoon joked one day, nudging you both. You shot him a glare, but even he laughed. “Nope. Not happening.”

The tipping point came one rainy afternoon. You were walking out of the studio, tired, hoodie soaked through from the drizzle. Heesung, distracted, bumped into you. His iced coffee spilled all over your favorite white hoodie. Your eyes went wide, and for once, Heesung didn’t grin.

“I—I’m so sorry,” he stammered, panic in his tone.

You wanted to scream. But later, in your locker, you found a brand-new hoodie. Neat, folded, with a small note tucked inside: “Sorry about earlier. Didn’t mean to ruin your favorite. - Heesung”

It wasn’t just the apology—it was that he remembered. That he cared enough to fix it. Slowly, the walls between you began to crumble. You started talking—normal, mundane conversation. Not perfectly polite, but real. You laughed at his ridiculous jokes, and he started to shrug off the teasing, letting you roll your eyes without snapping back.

And yet, some part of that old tension lingered, a spark that neither of you could fully ignore. You still fired back at each other with sharp words, playful insults, a private game that no one else understood.

Fans didn’t see it yet—they just knew the chemistry was undeniable. But behind the cameras, behind the practice rooms and quiet corridors, something new was forming. Something neither of you had expected: friendship. Maybe even more.

Weeks later, the MAMA Awards arrived. You were backstage, heart racing after your performance. The adrenaline hadn’t worn off when someone nudged you from the side. It was Heesung, looking unusually tense.

“You… your performance was good,” he said, stiffly, trying to sound casual. But his jaw tightened, and his eyes held that familiar edge.

“What’s your problem?” you asked, raising an eyebrow.

“I just…” he ran a hand through his hair, frustrated. “I’m trying to be okay with you. I’m trying, okay? Can you just… let me?”

For the first time, his usual pride and teasing fell away. You saw it—the honesty, the vulnerability. You blinked, caught off guard by the raw sincerity in his gaze.

“And… by the way,” he added, a small smirk breaking through, “I’m inviting you to my birthday party. Don’t think you can skip it.”

A week later, the party arrived—lights, music, laughter, and all of Hybe’s artists in attendance. Heesung spotted you across the room, and his usual playful energy returned, but there was a different edge this time—warmth underneath the teasing.

“You actually came,” he said, pretending to roll his eyes but his smile betrayed him. “I was starting to think you’d chicken out.”
