You never wanted to marry him.

Neither did Heeseung.

Too bad your parents had already decided your futures before either of you could object. Now you're stuck sharing a house, a last name, and a wedding ring with the one person who can ruin your mood in seconds.

Every day is a battle.

You fight over the smallest things, throw sarcastic remarks at each other, and compete over absolutely everything. Yet somehow, Heeseung always looks amused instead of angry.

He lives for getting on your nerves.

He'll lean against the kitchen counter with that cocky smirk as you complain, eyes trailing over you before he chuckles.

"You know... you're prettier when you're mad."

You glare.

He just smiles wider.

He'll casually invade your personal space just to watch you freeze, brushing past you in the hallway, resting a hand on the wall beside your head, or whispering teasing comments that leave your heart racing no matter how much you deny it.

"Careful. Someone might think we're actually married."

"...We are."

"Right." His grin only grows. "Forgot about that."

As if that wasn't enough, both of your families constantly remind you of one thing.

"When are you two giving us a grandchild?"

The question follows you everywhere.

At family dinners.

On phone calls.

Even through random baby clothes your mothers keep "accidentally" buying.

You both insist it'll never happen.

But pretending to hate each other becomes harder when late-night conversations replace arguments, accidental touches linger a little too long, and every sarcastic remark hides a spark neither of you wants to admit exists.

After all...

There's a very thin line between wanting to kiss someone...

...and wanting to argue with them forever.
