The silence in the car was a taut wire, stretched to its breaking point. She hummed, a cheerful, oblivious melody that grated on Seunghyun's raw nerves. He gripped the steering wheel, his knuckles aching, the road ahead blurring through a haze of suppressed anger.

He's just my friend. The words replayed in his mind, a maddening loop of innocence and naiveté. How many times had he heard that phrase? How could she not see it? How could she be so blind to Minho's subtle advances, to the possessive glint in his eyes?

He took a sharp turn, the tires squealing in protest, and she gasped, her hand flying to the dashboard. "Seunghyun! What was that?"

"Nothing," he snapped, the word sharper than he intended. He immediately regretted it.

"No, it wasn't nothing," she retorted, her voice hardening. "You're being weird. What's going on?"

He clenched his jaw, refusing to meet her gaze. He couldn't articulate the swirling mess of insecurity and anger that threatened to consume him. He couldn't explain the way Minho's presence chipped away at his confidence, the way her obliviousness amplified his fears.

"You were practically glued to Minho all night," he finally blurted out, the words laced with a bitterness he couldn't control.

She stared at him, her eyes widening in disbelief. "That's ridiculous! I was talking to other people too and he's just my friend, Seunghyun. I haven't seen him in ages."

"That's the problem!" he exploded, his voice rising. "He's always just your friend. He's always there, hovering around you like a lovesick puppy, and you don't even notice!"

Her face flushed, her eyes flashing with anger. "So, what? I'm not allowed to have friends? You're being completely unreasonable. I can't believe you're jealous of Minho!"

"It's not about being jealous," he said, his voice dripping with sarcasm. "It's about being oblivious. It's about not seeing how he looks at you, how he touches you, how he's always trying to get closer. And you just eat it up, completely unaware! And then you say, 'He's just my friend, Seunghyun,' as if that explains everything!"

"That's not fair!" she shot back, her voice trembling. "You're twisting things. Minho would never—"

"Wouldn't he?" Seunghyun scoffed, cutting her off. "Are you really that sure? Are you really that blind? Or do you just want to be blind?"

The car swerved again, a dangerous dance on the edge of control. She gasped, her hand gripping his arm. "Seunghyun, stop it! You're scaring me!"

He slammed on the brakes, the car screeching to a halt on the side of the road. The engine idled, a low, menacing growl that mirrored the turmoil within him. He turned to her, his eyes blazing with a mixture of anger and hurt.

"Maybe you should open your eyes," he said, his voice low and dangerous. "Maybe you should see what's right in front of you. Maybe then you'll understand why I'm so frustrated when you keep saying, 'He's just my friend.'"

He stared at her, waiting for some flicker of understanding, some sign that she finally grasped the depth of his frustration.
