What is the plot?

The episode opens with Detective Saeki Jin arriving at the abandoned Haikawa mansion in 2017, where police have discovered 13 skeletal remains of children buried in the garden. Saeki examines the bones, noting they are all children aged 10 to 15, and finds a strange mark carved into a tree nearby--a circle with intersecting lines resembling a family crest. He questions local witnesses who report hearing cries from the mansion over the years but never intervening.

Saeki enters the dilapidated mansion, searching rooms filled with dusty toys and child-sized beds chained to walls. He uncovers diaries written by children describing a man they call "Father" who brought them food but punished disobedience with isolation. Saeki pockets a photo of a group of children with a man whose face is scratched out.

Outside, Saeki is approached by Hasumi Kanon, a young woman in her early 20s who claims to be one of the survivors and refers to Haikawa Juuzo as her father. She insists Juuzo is innocent and was protecting the children from outsiders. Saeki questions her harshly about her whereabouts during the incident, and she reveals she escaped days before the discovery, hiding in fear.

Kanon leads Saeki to a hidden basement room untouched by police, showing child drawings depicting "Father" as a hero saving them from "monsters." She breaks down emotionally, clutching a locket with Juuzo's photo, and begs Saeki not to arrest him without proof. Saeki softens slightly, deciding to verify her story by checking survivor records.

Flashback to seven days earlier: Kanon, inside the mansion, argues with Juuzo about a boy named Taro who tried to run away. Juuzo locks Taro in a dark closet as punishment, while Kanon pleads for mercy, revealing her deep attachment to Juuzo as her rescuer from an abusive home. Taro screams for hours until he stops.

Back in present 2017, Saeki drives Kanon to the police station for formal questioning. En route, she recounts how Juuzo gathered the children from streets and orphanages, promising them a family. Saeki presses her on the deaths, and she admits some children died from illness, but Juuzo buried them lovingly.

At the station, forensic results confirm the skeletons died from starvation and dehydration over months, not sudden violence. Saeki confronts Kanon with this, accusing Juuzo of systematic neglect. Kanon defends him, saying he was overwhelmed after his wife died, and the children chose to stay.

A twist reveals another survivor, a boy named Ren, captured by police after wandering nearby. Ren, terrified, tells Saeki that Juuzo forced them to dig their own graves as "training" and killed Taro by locking him permanently after an escape attempt. Ren identifies the tree mark as Juuzo's signature from his cult-like teachings.

Kanon overhears Ren's testimony and rushes into the interrogation room, attacking him physically, screaming that he's lying to destroy their family. Saeki restrains her, and she confesses she helped bury Taro but believed it was mercy to end his suffering.

Saeki decides to raid Juuzo's suspected hideout based on Kanon's slip about a nearby cabin. He assembles a team and storms the location at night. Inside, they find fresh food supplies and more child drawings but no Juuzo.

Kanon, released on bail, sneaks back to the mansion alone. She digs up a buried box containing Juuzo's letter confessing he orchestrated the deaths to "preserve purity" after learning one child was reporting them to authorities. Devastated, Kanon burns the letter, deciding to protect his memory.

Saeki tracks Kanon to the mansion via her phone. He arrives as she sets a small fire to the drawings. In a tense confrontation, Saeki reveals DNA evidence linking Juuzo to multiple child abductions predating the mansion. Kanon pulls a knife, lunging at Saeki in desperation.

Saeki disarms her after a brief struggle where she slashes his arm. Pinned down, Kanon sobs that Juuzo saved her life and the deaths were accidents from their isolation. Saeki handcuffs her, reading her rights.

The episode cuts to 2024: A girl matching the survivor profiles goes missing, and Saeki, now older, finds the same tree mark at the new site. He stares at a photo of Kanon, released years ago, realizing the cycle may continue.

Final scene: Saeki visits Kanon in a remote house. She greets him calmly, inviting him in, where child voices echo faintly from upstairs. Saeki draws his gun as the door closes behind him.

What is the ending?

In the finale of Episode 4 of A Suffocatingly Lonely Death Season 1 (2024), Detective Jin Saeki confronts the truth about the Haikawa Residence Incident in a tense hideout standoff, leading to Juzo Haikawa's shocking self-revelation and Kanon Hasumi's heartbreaking betrayal, as the mysterious mark seals the cycle of hidden crimes linking 2017 to 2024.

Now, let me take you through the ending scene by scene, as the shadows deepen in that dim Tokyo hideout where runaways huddle, the air thick with the scent of damp concrete and unwashed clothes, the flickering fluorescent light casting long, jagged shadows on peeling walls.

The scene opens in the 2024 hideout, a cramped underground room lit by a single bare bulb swinging overhead. A group of young runaways--disheveled teens with hollow eyes and tattered hoodies--cluster around a makeshift table littered with empty ramen cups and cigarette butts. Among them is a girl with stringy black hair and bruised knuckles, fidgeting nervously as she glances at the door. Suddenly, she stands, grabs her backpack, and slips out into the rainy night without a word, her sneakers splashing in puddles as the door creaks shut behind her. The others exchange uneasy looks but say nothing, the silence broken only by the distant rumble of a train.

Cut to Detective Jin Saeki, his trench coat soaked from the downpour, face etched with exhaustion and unyielding determination, pulling up in an unmarked car outside the hideout. His strong sense of justice burns in his narrowed eyes as he grips the steering wheel, flashbacks flickering: the 2017 discovery of 13 skeletons in the Haikawa mansion, their bony frames curled in starvation, each marked with that eerie symbol--a circle pierced by three lines, carved into the floorboards. He steps out, flashlight cutting through the darkness, and enters the hideout stealthily through a side door.

Inside, Jin scans the room, his boots quiet on the gritty floor. The runaways scatter slightly, but one boy, pale and twitchy with a fresh scar on his cheek, points silently toward a back room partitioned by hanging tarps stained with mold. Jin pushes through, gun drawn low, heart pounding with the weight of seven years chasing ghosts.

In the back room, dimly lit by a lantern on a crate, stands Kanon Hasumi, her once-bright eyes now shadowed with desperation, dressed in a faded sweater that hangs loose on her slender frame. She's facing Juzo Haikawa, the missing homeowner, his silver hair disheveled, face gaunt and lined with secrets, wearing a threadbare robe that smells of earth and decay. He's drawing the mysterious mark on the wall with a piece of chalk, his hand steady despite the tremor in his voice. Kanon kneels before him, tears streaming down her cheeks, whispering, "Father, you saved me when no one else would," her voice cracking with the raw emotion of abandonment turned to blind loyalty.

Jin bursts in, weapon raised, shouting for Haikawa to freeze. Haikawa turns slowly, a faint smile on his lips, no fear in his eyes. "Detective Saeki," he says calmly, "you've come for the truth." He reveals he took in runaways like Kanon, offering them shelter from abusive families and society's cruelty, but a hidden rot festered: not him, but a trusted inner circle among the children who enforced brutal rules, starving dissenters and marking the bodies to frame him. The 13 skeletons were victims of that internal purge, their deaths a suffocating loneliness imposed by peers desperate to protect their fragile haven.

Kanon rises, her face twisting from adoration to rage, pulling a knife from her sleeve--sharp, glinting under the lantern. She lunges at Jin, screaming that Haikawa is innocent, her strikes wild with the ferocity of someone whose savior cannot fall. Jin dodges, disarming her with a precise twist, but not before she slashes his arm, blood soaking his sleeve. She collapses to her knees, sobbing, her world shattering as Haikawa admits partial fault: he knew of the abuses but turned a blind eye, his paternal love blinding him to the monster he'd created.

Haikawa then takes the knife from the floor, carving the mark deeper into his own palm, blood dripping onto the concrete. "The cycle ends with me," he mutters, and in a swift motion, plunges it into his chest. He slumps against the wall, eyes glazing over, body going still as a pool of blood spreads, the mark smeared in crimson on his hand.

Jin, clutching his wound, radios for backup, his voice hoarse. Kanon crawls to Haikawa's body, cradling his head, her wails echoing as police sirens wail closer. She is arrested on the spot, handcuffs clicking around her wrists, her face a mask of numb devastation, led away into the rain as the hideout is swarmed by officers.

Jin stands alone amid the chaos, staring at the mark on the wall, the rain pattering on the roof like falling tears. His brother, Sosuke Takimoto, arrives late, pushing through the crowd, his face pale with worry, placing a hand on Jin's shoulder--their bond unspoken but ironclad.

Fates at the end: Juzo Haikawa dies by his own hand in the hideout, his body marked by the symbol as he bleeds out. Kanon Hasumi is arrested for assaulting Jin and complicity in the cover-up, dragged away in cuffs, her admiration for Haikawa destroyed. Jin Saeki survives his injury, case partially closed but haunted by lingering mysteries, driving off into the night with resolve unbroken. Sosuke Takimoto remains safe, supporting his brother from the sidelines. The runaways in the hideout are questioned and dispersed by police, their fragile community shattered. The missing girl from earlier is implied recovered off-screen, the mark's reappearance halted--for now.
