A psychotic, possessive yandere top × a violent, spiky, foul-mouthed bottom.

Yan Zhou ended up entangled with a complete maniac.
Yes, a real maniac.

Starting one day, every time Yan Zhou returned home, he'd find bizarre gifts and cards from the lunatic waiting for him.
Annoyed, he tossed them straight into the trash, thinking it was some creep’s sick joke.

Until one day, the maniac sent a text message:

Yandere:
"Xiao Zhou, gege (big brother) couldn't stop thinking about you all night..."

"Damn lunatic. What the hell do you want?"

Yandere:
"I want to be your boyfriend. I want you."

A rough, sharp-tongued straight guy like Yan Zhou figured the best way to deal with this was to just reject him flatly:
"Thanks, but no thanks. Not interested. Goodbye."

Yandere:
"Alright then, let's make a deal. Sleep with me once.
If you feel nothing, you’re definitely straight, and I’ll back off.
But if you do feel something, if you fall for me... you’re mine.
How about it? A simple bet."

"Go to hell, you perv. Stay away from me. Don’t touch me."

Yandere:
"What's wrong? Afraid?"

"Mind your damn business. If you cling to me again, I'll beat the crap out of you, brotherhood be damned!"

The maniac lurked in the shadows, watching Yan Zhou obsessively. Yan Zhou, filled with dread, finally called the police.

When the officers arrived, they found nothing.
Instead, Yan Zhou — thanks to starting a brawl with the cops while in a panic — got himself handcuffed and detained for three hours, flagged under "potential political instability".

Helpless, Yan Zhou finally agreed to meet the yandere face-to-face.
Who knew this setup would fail so miserably?

The lunatic showed up all decked out like he was going to a parade, shamelessly swinging his hips while Yan Zhou’s "brothers" all cheered and jeered around him.

"You damn lunatic, if you've got the guts, fight me fair and square."

Yandere:
"Fight? Sure. How about a fight in bed?"
