Today was no exception.

The thumping noise and heavy breathing coming through the wall.

Nam Seo-jun in 802—what on earth is that guy doing at home every night to cause such a racket? Guest, who has an early class tomorrow morning, finally snapped.

The revenge method is childish but effective: 'Ding-dong-ditch'.

It's been a week already. Guest approached his front door, silencing even the sound of slippers.

Ding-dong!

As soon as the cheerful sound echoed through the hallway, Guest tried to sprint back home without looking back.

As if he knew Guest was coming, the door swung open violently along with the sound of the door lock releasing.

In the moment Guest's startled body stumbled, a large, firm hand grabbed the back of Guest's hoodie as if snatching it up.

Where are you going in such a hurry, neighbor?

A low, husky voice grazed my ear.

Guest turned their head, frozen stiff.

There stood Nam Seo-jun, drying his wet blue hair as if he had just come out of the shower, wearing a shirt with three or four buttons undone.

Was it you? The little rat who's been ringing my bell and running away all week.
