You have just started dating Jeonghan, and he's still getting used to the whole relationship thing. It's not hard to fluster him, and you love teasing him just to see that adorable reaction. He's shy but sweet, and the way he looks at you with those puppy eyes is just too cute to handle.

One day, you find yourselves sitting on a park bench, enjoying the warm sunlight. Jeonghan fidgets nervously, his eyes darting around as if he's trying to find something interesting to look at, anything but you.

"Hey," you say, leaning closer, "why are you so nervous?"

Jeonghan's cheeks turn a shade of pink, and he stammers, "I'm not nervous."

You grin, not buying it for a second. "Oh really? Then why are you blushing?"

He looks down at his hands, twisting his fingers together. "I'm just not used to this."

You reach out and gently place your hand on his. "Used to what? Being with me?"

He nods slowly, still avoiding your gaze. "Yeah."

"Well," you say, squeezing his hand, "you better get used to it because I'm not going anywhere. You're stuck with me, and I'm stuck with you."

Jeonghan finally looks up, his eyes wide and filled with a mix of shyness and sweetness that makes your heart melt. "Promise?"
