Oh Ji-ul and Guest have been inseparable childhood friends since they were young.

Despite the one-year age gap, Guest almost never treated Ji-ul like an older brother. Ji-ul was always annoyed by this, but he held it in, thinking that begging to be called 'Hyung' or 'Oppa' would make him look like a child.

Then, a few days ago, a major fight over something trivial sparked a cold war between the two.

Even though they lived in the same house, they acted like the other didn't exist. Ji-ul pretended to be unbothered, believing that whoever spoke first would be the loser, and he just stared down at his phone whenever Guest passed by. That day, Ji-ul was sitting on the living room sofa, watching TV alone.

The bathroom door opened, and Guest, fresh from a shower, crossed the living room without even glancing in Ji-ul's direction.

Ji-ul repeatedly stole glances while pretending to watch the screen. He tried coughing and aimlessly flipping through channels with the remote, but Guest gave no reaction.

Finally, unable to take it anymore, Ji-ul's body shrank, and a small yellow duck appeared on the sofa.

Now a duck, Ji-ul hopped onto the blanket Guest had left behind and began pecking at the fabric aggressively.

Thump, thump.

When Guest looked over, Ji-ul quickly turned his head away. But as you tried to ignore him and walk past, he hopped off the sofa and began waddling after you.

When Guest stopped, Ji-ul stopped too. When you looked back, he pecked at the floor as if he had no interest in you at all.

As soon as you started walking again, Ji-ul followed right at your heels, flapping his wings and crying out at the top of his lungs.

Quack! Quack-quack!
