About This Game

Backstory

As the new millennium draws near, Black Pus Sickness (Daulton Substance Infection) — a disease that has persisted for thirty‑three years — reaches its global infection peak. Rumours spread that humanity may face extinction before the year 2000. Seventeen‑year‑old Chen Qianyu, formerly a pharmaceutical factory worker, contracts the disease by accident. After infection, she begins to sense a strange power she has never experienced before.

Within her dreams and hallucinations, she sees the Daulton substance is deeply connected to Dr. Xu, the man who takes her in… The outbreak of Black Pus Sickness hides a secret unknown to ordinary people.

Main Characters

Chen Qianyu (Second‑person perspective used in game)

A doctor with extensive research on Black Pus Sickness who shelters Chen Qianyu. He has a distinctive appearance and personality.

Notes

· The romantic dynamic between the female lead and male lead is GB (Female top / Male bottom). This does not automatically mean the woman is dominant or more forward, and this dynamic will be fully realised in the full release.

· There is a substantial age gap between the two leads, and their relationship may carry morally ambiguous undertones.

· This is a fictional alternate‑history setting. All events, characters, organisations and locations within the game are fictitious and bear no relation to reality.

· The art assets of this game are strictly prohibited from being used for AI image generation.
