Xiao Yao is in the Emergency Room, reviewing some files at the desk. Suddenly, the door bursts open and a woman rushes in, her face covered in bruises, screaming desperately.
_Help me! Please, help me! He has my daughter!
XY: (Quickly standing and approaching her) Oh my God! What happened? Who has your daughter?
_My husband. He beat me and took our daughter. I fear for her life.
XY: (Looking at a nearby nurse) We need help immediately.
The nurse nods and runs off to call the police.
Police Officer: Ma'am, we can't do anything. He's her father. We can't charge him with kidnapping.
_Please, I beg you…!
XY, deeply moved, calms the woman.
XY: I will find help. We will get your daughter back. I promise.
Minutes later, XL rushes into the room.
_ What's going on, Xiao Yao?
XY: (Pointing at the woman) Her husband beat her and has their daughter. You could help us.
XL makes it clear to XY that his help was meant for her, not just anyone.
XY: Please, I'm asking you… from now on, I'll help you every time you ask.
XL stares at XY for a long moment, then nods.
XL and XY arrive at the husband's house. The door is closed, but screams and cries can be heard from inside.
XL: (To XY) Stay here. I'll go in.
XL forces the door open and enters. He finds the husband threatening the little girl.
Man (shouting): Stop crying… be quiet!
Girl (crying): Mommy!
Without hesitation, XL lunges at him. They struggle; XL takes a few blows, but finally manages to knock the husband out and rescue the girl. XY checks the child's condition. Then they head to the hospital.
XL: (Carrying the girl in his arms) Here you are. You're safe now.
The woman runs forward and hugs her daughter, crying with relief.
Woman: Thank you, thank you!
XY: (Noticing XL's injuries) You're hurt.
XY is tending to XL's wounds in a small treatment room. The tension between them is palpable.
XY: (Gently) Does it hurt a lot?
XL: (Smiling slightly) I'm fine.
XY: Thank you.
They look into each other's eyes. XL leans in slowly, their lips almost touching, when a nurse suddenly enters holding an envelope.
Nurse: Sorry, doctor. Here are the lab results.
XY quickly steps back, slightly flushed, and takes the envelope.
XY: Thank you.
They both review the results at a table.
XY: (Frowning) The toxicity levels are high, but we can't identify the exact metal.
XL: (Thoughtful) I've heard rumors of contamination in that area. I should go investigate.
XY: (Looking at him with concern) We can't wait. Are you sure?
XL: (Nodding) Yes. I'll go diving and see what I find.
XY: (Firmly) I'm coming with you.
In the early morning, aboard a small boat, accompanied by the man steering it. XL is ready with his diving gear. XY watches him anxiously.
XY: (Shouting) Be careful, XL!
XL: (With a reassuring smile) I always am.
XL dives into the water and descends deep below the surface. In the distance, he sees suspicious containers on the seabed. He collects samples. As he tries to return to the surface, he realizes his oxygen is running out.
XY watches her clock, worried.
XY: (To the boatman) XL is taking too long to come up.
Suddenly, she sees a figure floating.
XY: (Screaming) XL!
She jumps into the water and swims toward him. She pulls him out, and with the man's help, they lift him onto the boat. XY begins mouth-to-mouth resuscitation.
XY: (Desperate) Come on, XL. Breathe, please.
After a few moments, XL coughs and starts breathing. XY hugs him tightly, relieved.
XL: (Weakly) Did you find anything?
XY: (Smiling through tears) Yes. I found you.
They embrace tightly, knowing they've shared an experience that has brought them even closer.
Later, on the shore, they talk.
XY: XL, we have to report this to the authorities.
XL: I won't.
XY: Why?
XL: (Mockingly) You're very naive, Doctor.
XY: (Angry) Yes, I am naive… do whatever you want.
XL takes XY home. In front of the building, they stand in silence, just looking at each other. XY turns and walks away. XL watches her as she leaves.
XY: (Already in her apartment, murmuring) Idiot!
17: (Hearing her) What's wrong, XY? Is everything okay?
XY: Nothing. Just remembering an idiot I met.
17: Don't think about it anymore. Come eat.
XY smiles, sits at the table, and they talk about how their day went.
That night, XL sits on his motorcycle, his gaze fixed on the building where XY lives.
