I set you up on a blind date, and you've managed to overcome all the weirdness?

"Never mind, this is a special mark that your older sister gave you."

"But little brother, now that you've accepted my mark, what will you do next time you come here...?"

"If you still smell of another woman on you, I promise I'll chop your unfaithful heart into mincemeat."

The blood moon faded, and the real moon peeked out from behind the clouds.

Lin Yan stood there, touching the red lipstick mark on her neck.

It's cool and refreshing, which is quite comfortable.

He picked up his phone, opened the selfie camera, and rubbed it against the screen.

Sure enough, it can't be washed off.

He looked at the distant night sky and fell into despair.

"If Saya sees this..."

Lin Yan complained incessantly.

Feeling guilty, he turned up his collar to cover the lip print, looked around to make sure no one was nearby, and then ran away in a flash.

Back at the apartment, the first thing Lin Yan did was rush into the bathroom.

He acted like a bathhouse attendant encountering a southerner entering a bathhouse for the first time, frantically smearing the lip print on his neck.

Half an hour later, the skin was almost rubbed raw, but the red lipstick mark remained completely untouched, as if it were embedded in the flesh, and was very obvious.

"Oh no, this is a top-tier tattoo."

Lin Yan slumped on the sofa, wanting to cry but having no tears.

Fortunately, Chu Chu has been busy cleaning up the mess for that Deep Sea Siren account on the dark web these past few days, so she hasn't had time to check up on him.

As for Saya, according to Chu Chu's secret report, that old lady is too caught up in the killing spree to come back anytime soon.

Lin Yan barely managed to get a few days of reprieve from his death sentence.

Even though she could be ambushed by Saya at any time while at home, Lin Yan decided to go to work as usual, simply because she loved her job.

To avoid arousing suspicion, he slacked off at his seat after clocking in.

He only leaves work after everyone has left, trying to avoid any possibility of interacting with people.

That afternoon.

Lin Yan was slumped in his chair, browsing local forums and reading urban legends about the campus, trying to find the weakness of the senior in red.

The office door was pushed open.

Su Qinghan walked in carrying a stack of files, her face still as icy as ever.

"Oh my, isn't this Coach Su? Is he here to give me work again?"

Lin Yan quickly turned his phone face down on the table. If he was caught slacking off, it wouldn't be called slacking off anymore, and he felt that this was sacred.

"Commander Chen said he wouldn't assign me any tasks these next few days, and that I should rest and recuperate."

Su Qinghan didn't waste time joking with him and pushed the file in front of him.

Dust flew everywhere, and Lin Yan covered his nose with his notebook.

Goodness, this is an old file from at least a decade ago, it's covered in dust.

"Now that you have the highest authority, and given the recent unusual fluctuations at the old campus that have caused quite a stir, you'd better take a look at this file."

Su Qinghan's sharp eyes swept over Lin Yan's collar, which was also turned up high in the room.

Lin Yan immediately stopped smiling. This woman was truly terrifying; she definitely knew he had been to the old campus!

"Old campus? What old campus? How come I don't know about it?"

He tried to remain calm and casually picked up a document and opened it.

The first page is a black and white photograph, seemingly taken at the crime scene.

Judging from the appearance, the office conditions are not very good; the photos kept as records are not even in color.

The photo shows a girl's school uniform, carelessly tossed aside next to the water tower on the rooftop of the teaching building. The clothing design has a distinctly 1990s style.

The school uniform was covered in large patches of dried blood, and the black and white texture gave it a feel of an old-fashioned ghost movie.

"This school uniform..."

Lin Yan frowned slightly. The familiar smell of blood seemed to have traveled through the photograph for thirty years and entered his nose.

Thirty years ago, the predecessor of the old Red Star Medical College was Jiangcheng Women's University.

Su Qinghan pulled up a chair and sat down, her opening remarks sounding like she was telling a particularly frightening ghost story. (Please don't kill me, censors, I'm already going crazy from all the editing!)

"Back then, a series of murders occurred at this university."

"Five students were brutally murdered."

"When these five people were found, they had already lost vital signs."

"And the owner of this school uniform is the sixth victim."

"He is also the only one whose body has not been found to this day."

Lin Yan picked up the photo and looked at it from left to right, following the light, as if trying to confirm something.

Looking at the familiar style in the photo, he recalled the figure in a bright red dress on the rooftop.

It turns out that it wasn't a red dress at all!

It turns out the senior wasn't joking; she really does sew!

"After that case, the university was urgently abandoned and later converted into the old Red Star Medical College."

"But that school building became a restricted area on campus."

Su Qinghan tapped her hand lightly on the file, carefully observing Lin Yan's reaction.

"Anyone who tried to explore that building at night either disappeared or was found dead a few days later."

"This is the origin of the most widely circulated urban legend from more than 20 years ago, the 'Red-Clad Senior'."

The office was silent. Su Qinghan looked up and scared away a group of agents who had secretly gathered around.

Lin Yan swallowed hard, feeling the hickey on his neck burning faintly, as if it were mocking his ignorance.

He always thought that the senior in red was just an oddball who was born because of heartbreak or school bullying.

Most of the weird things that happen at school follow this pattern.

To some extent, manipulating someone's romantic mind and school bullying are the same level of wrongdoing.

Who would have thought that such a cruel serial murder case was hidden behind the senior student?

"Special Envoy Lin"

Su Qinghan placed both hands on the desk, looking down at Lin Yan, her eyes seemingly able to see through people's hearts.

"I don't care what you're up to with your social skills over there."

"But I must remind you that the core of that bizarre obsession is also unprecedented in the records of the General Administration."

"Her level of danger is definitely no less than any of the bizarre creatures you've ever dealt with."

"If you want to play with fire with her..."

Su Qinghan turned and walked towards the door, leaving behind a cold piece of advice.

"Please be prepared to use artificial skin when the authorities collect your body."

Lin Yan put the file into the drawer only after Su Qinghan left.

He reached up and touched his neck, feeling excruciating pain.

Playing with fire?

He wasn't playing with fire; he was being played by fire!

However, the thirty-year-old file that Su Qinghan brought provided Lin Yan with a crucial piece of information.

There must be more to the case of the senior in red back then, and her obsession is probably inextricably linked to the case.

Six people were clearly dead, but her body was the only one that could not be found.

And why is she now sewing her skin back onto that school uniform?
