I suggest you investigate; this person doesn't seem to be a first-time reborn individual.

[The First Story]

The scene cuts to a dimly lit alley.

At 2:30 a.m., in an urban village, a middle-aged man squatted by the roadside, covering his face with his hands.

The police officer standing next to him offered the man a cigarette: "The surveillance footage shows her heading north. There are too many forks in the road there, and we're still checking them one by one."

The man didn't take the cigarette. As if he suddenly remembered something, he took out his phone, opened Momo, and clumsily typed.

"My daughter is missing. She's four years old and wearing a red cotton-padded jacket. Does anyone live north of Sunjia Lane? Could you please keep an eye on her?"

The scene shifts to a late-night urban village, where countless people are watching what's happening in the neighborhood through the lit windows.

Three minutes later, a message popped up on the man's phone.

It's a photo of a little girl in a red cotton-padded jacket, squatting next to a trash can at the corner of an alley. It's clearly taken from an upstairs window.

The man glanced at the distance—137 meters—and immediately dashed off like a madman.

When they arrived, they found their daughter asleep leaning against a trash can, with a young woman squatting next to her, shining a flashlight on her.

The man knelt down, hugged his daughter tightly in his arms, and trembled uncontrollably.

The young woman exhaled and rubbed her hands together: "I live upstairs. I saw your message and just opened the window to take a look."

The image freezes.

Subtitle: He opened the "People Nearby" feature to find his daughter.

[The Second Story]

Nine o'clock at night, at an intersection.

An old lady was squatting under a street lamp, with a few bunches of green vegetables in front of her. The wind was a bit strong that night, and she wrapped her coat around herself again and again.

A woman was riding her electric scooter home from get off work when she stopped at a red light at the intersection and bought one on the spot.

She walked a few dozen meters, then looked back. The old woman was still squatting there, and there was no one else on the street.

She took out her phone, opened Momo, and posted a status update nearby.

"There's an old lady selling vegetables at the entrance of the alley on Xinhua Road. She looks to be over seventy. Does anyone live nearby and want to buy some vegetables? We'd like to help her get home as soon as possible."

The video started to speed up.

Three minutes later, a young man on an electric scooter stopped in front of the old lady and bought some groceries.

Five minutes later, a woman walking her dog squatted down and picked up two handfuls.

Ten minutes later, a young couple walked over and bought the rest.

The old woman stood up, picked up her empty basket, and slowly walked into the night.

The woman who sent the message stood at a distance, watching her figure disappear.

Subtitle: She opened the "People Nearby" feature so that an elderly woman could go home earlier.

[The Third Story]

It was 11 p.m. in a small alley without streetlights.

A girl had just finished get off work and was walking home from the subway station when she heard footsteps behind her, getting closer and closer.

She turned a corner, and the people behind her turned a corner too; she quickened her pace, and the people behind her quickened their pace too.

She took out her phone, opened Momo, and sent a group message to people nearby: Someone is following me in XX alley, help!

She continued running forward when a young man in a convenience store uniform suddenly rushed out of the alley ahead, carrying a mop handle. He stood in the middle of the road and shouted at her from behind, "What are you doing?!"

The footsteps behind the girl stopped, and then she heard the footsteps of the person following her walking away.

The convenience store clerk ran over, panting, "I saw your message. The convenience store is right at the alley entrance, and it shows that we're less than 100 meters apart."

Immediately afterwards, two more people rushed out of the alley: a woman carrying a spatula and a man in pajamas.

The older woman looked around: "Where is he? Where is he?"

The older man, panting, said, "I live on the second floor. I was brushing my teeth when I saw my phone, so I came downstairs."

The older woman shook the spatula: "I was only halfway through cooking the vegetables when I turned off the heat and ran out."

The girl stood under the streetlight, looking at the three people, her voice choked with emotion, unable to speak.

The screen switched to her phone screen, showing dozens of unread messages, all sent in the past few minutes:

"Are you alright, young lady?"

"Should we call the police?"

"I'm coming out right away!"

Where are you?

发信人距离：83米、142米、67米、215米、31米……

Subtitle: She opened the "People Nearby" feature to call for help; the people nearby opened the "People Nearby" feature to save her life.

[The Fourth Story]

The last story is a little different from the first three.

The image shows a young man in a construction site shed in the background.

He tossed and turned, unable to sleep. His phone screen showed three calls to his father, but no one answered.

My father lives alone in our hometown and has a heart condition.

He opened Momo and clicked on a new feature: location spoofing. He set his virtual location to the old house where his father lived.

On the screen, a series of avatars appeared, all of whom were people near the father's house at that moment.

He clicked on the most recent male contact, hesitated slightly, and typed: "Bro, I'm out of town and can't go back. My dad's home alone, and no one answers the phone. Could you please knock on his door for me?"

The person on the other end quickly replied: "...Are you serious?"

He typed quickly: "Please! My dad has a heart condition, I'm afraid something might happen. Just knock on the door and check on him!"

The other party replied: "Send me the address."

He sent the address and then stared at the other person's profile picture as the distance value began to change.

237米、185米、136米、78米、32米……

Then, a message popped up: "Your door is locked, and no one has answered the door despite knocking for a long time."

His heart jumped into his throat.

Then came another message: "I heard a phone ringing inside. I just went around to the back window and saw the lights were on, and someone was lying on the floor!"

His hands began to tremble: "Please, help me! Call an ambulance!"

The message from the other end came almost simultaneously: "Don't panic, I kicked the door open, I've already called 120, the person is still breathing."

Then a photo was sent: in a dimly lit room, an old man was lying on the floor, and a young man was squatting next to him, holding the old man's hand.

He looked at the photo, and tears immediately streamed down his face.

Ten minutes later: "The ambulance has arrived. I'll go with it to the hospital. I'll call you when we get there."

At three in the morning, the phone rang:

"Hey bro, your dad had a heart attack. He would have died if we'd been ten minutes later. The surgery's done now, and the doctor says he's fine."

He asked, his voice choked with emotion, "What's your name?"

The other person paused for a moment, then smiled: "I'll call someone nearby."

The phone hangs up.

【End】

The screen changes.

The protagonists of the four stories sit side by side on a bench.

A reporter squatted down in front of them, holding a microphone: "Hello, gentlemen. We understand that you have all used Momo to help others or been helped by others. I would like to ask a question."

"What do you think love is?"

The four exchanged glances, but no one spoke first.

The four-year-old girl squirmed and said in her childish voice, "I know!"

Everyone looked at her.

The little girl looked up at the camera and said, word by word:

"Love is having someone by your side!"

The lights came on, and the entire venue fell silent.

Three seconds, five seconds, ten seconds.

Then applause started in one corner and quickly spread throughout the entire venue. Thousands of people clapped at the same time. Some stood up to pay their respects, some wiped away tears in the corner, and many more clapped their hands frantically.

The applause lasted for a full minute.

Lin Ran walked out from the side of the stage and stood under the spotlight in the center of the stage.
