I Hear the Trash Can Refreshes Every Day?

Temporary blurb:

Ling Nai is an utterly ordinary office worker.

He has a mysterious friend who is never around, and his hobby is... rummaging through trash cans.

Even though bizarre, downright chilling things keep happening around him, Ling Nai can still recite the Core Socialist Values fluently and insist that the world is normal.

One day, on his way home after working overtime, Ling Nai runs into his friend in an alley.

A man in a black hat stuffs his friend's corpse into a trash can right in front of him.

The clock strikes midnight out of nowhere.

A voice rings out:

[Game progress reset.]

The corpse in the trash can is gone.

His friend climbs out of the trash can.

[Mission failed. Punishment issued.]

The black-hatted man explodes right in front of him, filling the air with a mist of blood.

His terrified eyeball rolls to Ling Nai's feet, leaving a bloody mark on his shoe.

His friend, who has just stood up, grins and pats him on the shoulder.

"So you like rummaging through trash cans too, Ling Nai-kun."

Ling Nai: "..."

A trash can for rummaging through passwords.

You Peng, codename "Faraway."

The only madman in the [Cleaners] organization.

One second he's grinning and throwing an arm around you, the next he's sentencing you to death for entering a room with your left foot first.

Whenever his name comes up, everyone gets a headache.

Then this madman disappeared without explanation for a month. When he returned, he announced that he'd found a friend.

The friend seemed shy, ordinary, honest, and refined, the complete opposite of You Peng.

Everyone was delighted that the madman wouldn't be able to torment them anymore.

They were celebrating too soon.

Ling Nai is an out-and-out pervert too.

A pervert with a madman... The organization is doomed.

But they don't know that from the very start, this pair of best partners reborn from death never planned to let the organization survive.

[Fake ordinary person x real big shot]

Genre:

[A couple who can make everyone groan with one of them in the room, and set the whole place on fire (literally) with both of them there. Maybe one of them kills, and the other buries the body (?)

Clever, green-tea, domineering top x angelic bottom who fights back]

[Trying this type: refined, scholarly top x sweet, secretly wicked bottom =///=]

The two of them together are probably partners in crime (not really):

The bottom has dimples and little tiger teeth when he smiles, but he can wield a knife without hesitation, smiling sweetly even with blood on his face.

The bottom prods the corpse: "Hey, he stopped talking."

The top rolls up his sleeves: "...Don't drag him around. I'll take care of it. Go wash your face. You're filthy."

The bottom pauses, drops everything, then smears grime all over the top's face.

The top deals with the corpse while the bottom smears his face: "...I'm not dirty, but I don't like you having someone else's stuff on you. Blood either."

Only then does the bottom hum a tune and go wash his face.

In a word:

If you leave it running, it's a cheat? If you're bad, practice more!

Theme: Go find, go find, go find a friend. Find a good friend.
