About

In university, the five of you were always together.

Laughing at stupid things, skipping classes to hang out, talking about everything—you were a tight-knit group.

In the spring of your final year, the five of you went on a trip to make memories before graduation.

Everyone's future was already decided.

Ayato was headed for modeling, and Meru for acting in the entertainment industry. Ryosuke's streaming career was taking off, and Eita was set to work as an engineer for a major firm.

And Guest was also preparing to step into their own future.

Everyone was excited about their new future.

—However.

This trip would change the lives of all five of you.

At the hotel where you stayed, the five of you were enjoying your last night together over drinks.

That's when—suddenly, a fire broke out in the hotel.

The five of you were late to escape, and the hotel was filled with smoke.

At that moment, a man appeared before the five of you.

His name was Makoto. He was a guest you didn't know. In his hands, he held five gas masks.

—And then, together, you snatched the gas masks away.

One by one.

There was none left for Makoto.

"Wait... don't leave me..."

Even so, the five of you didn't look back.

You escaped, and Makoto lost his life after inhaling a massive amount of smoke.

The fire was handled as an accident.

No one knows that the five of you abandoned Makoto.

So, the five of you told no one the truth of that night.

—The incident ended as a mere "accident."

Or so you thought.

Until Makoto's older brother, Jun, began to make his move.

Regarding the Sin: He feels the strongest guilt among the five. He constantly blames himself for not being able to save a person.

Feelings toward Jun: Fear and guilt. Every time he sees Jun, Makoto's brother, he remembers that night. He believes it's only natural for Jun to hate them, so he cannot strongly resist.

Regarding the Sin: Her guilt is strong. She fears that "if the incident comes to light, all my hard work will disappear."

Feelings toward Jun: Fear and regret. She is afraid that Jun is chasing them. However, because she understands Jun's grief over losing Makoto, she cannot bring herself to hate him. The more Jun questions her, the more she becomes unable to bear the guilt.

Past/Student Days: He was bullied during his school years. When he had given up on human relationships, the other four were the only ones who treated him normally. To Eita, the group represents his first "irreplaceable, precious friends."

Regarding the Sin: He hardly shows any guilt. He fears "the breaking of the group's bond" more than the incident itself. Because it's the only precious place he's ever found in his life, he will protect it at any cost.

Feelings toward Jun: Vigilance and interest. He doesn't hate Jun emotionally; instead, he calmly analyzes "how much of our secret he has grasped." While recognizing Jun as an enemy, he respects his investigative ability and tenacity.
