About This Game

[h1]This isn't a lab accident. It's a summoning ritual.[/h1]

[b]Xiao Ming[/b], a senior biology major and self-proclaimed survivalist, thought he was working on an ordinary thesis — babysitting a batch of "classified fungal samples" shipped by his father from Russia. Adjust the temperature. Adjust the humidity. Adjust the pH. Write 200,000 words of observation logs.

Until his childhood friend [b]Hua Jia[/b] burst in with a bag of peaches and kicked over a 5-liter bottle of industrial ammonia —

[b]Six girls walked out of the petri dish.[/b]

They held jade-carved boarding passes and stood on official university documents, introducing themselves as this year's interdimensional exchange students at Wujiang University, numbered 001 to 006.

His older sister — also the university's Academic Affairs Director — adjusted her glasses and handed him a red-stamped A4 form:

[i]"Mom, Dad, and I lied to you for an entire year. Your real thesis starts now."[/i]

[h1]⏳ Four weeks. The clock is ticking.[/h1]

[list]

[*][b]Task 1:[/b] Settle six interdimensional exchange students into student life — dorms, meal cards, socialization, the works.

[*][b]Task 2:[/b] Find a [i]normal human girlfriend[/i] to prove you're qualified to guide them through human society.

[*][b]Task 3:[/b] [b]Don't blow up the lab a second time.[/b]

[/list]

Fail any of the above? Your diploma gets withheld, and you go home to marry Hua Jia — the girl who can kick a cow into the sky.

[h1]👥 Meet the Cast[/h1]

Wujiang University. A top-3 institution. Heavily female-skewed. Over the next four weeks, Xiao Ming will meet:

[list]

[*][b]🍄 Six Interdimensional Exchange Students[/b] — Amanita, Bamboo Fungus, Dry Mushroom, Lingzhi, Matsutake, and Lanmaoa. They used to be mycelium. Now they're enrolled students with IDs.

[*][b]💪 Hua Jia[/b] — Childhood friend. Star athlete. Can carry grown adults like luggage. Officially designated "fiancée candidate" by both families.

[*][b]💻 Tang Maimai[/b] — "PC repair from ¥30, no job too shady" — yet her toolbox costs ¥12,000. Something doesn't add up.

[*][b]📏 Ji Mingxue[/b] — Iron-fisted student council president. Carries the Student Information Disclosure Handbook during dorm inspections.

[*][b]🎨 Li Xinghui[/b] — Art PhD candidate. So elegant every gesture looks like it came from an etiquette textbook.

[*][b]🔬 Yu Qingling[/b] — Lab supervisor PhD. Writes 7-page incident reports accurate to the milliliter.

[*][b]👻 An Ruowei[/b] — Stood at the end of the hallway for 5 minutes. Nobody noticed her.

[*][b]😈 Lilia[/b] — A succubus-themed VTuber who streams... CET-4 English vocabulary. A classmate of yours, somehow.

[/list]

And [b]Older Sister[/b] — the one who knew everything from day one, but kept her own brother in the dark for an entire year, for KPI reasons.

[h1]✨ Features[/h1]

[list]

[*][b]🌏 Six Language Support[/b] — Chinese, English, Japanese, Russian, French, Spanish. Switch instantly in-game.

[*][b]🎙️ Fully Voiced Main Story[/b] — Every line of dialogue in the main route is voice-acted.

[*][b]🎭 Multi-Route Narrative[/b] — Seven independent character routes, each revealing a piece of the bigger mystery.

[*][b]🏛️ Gallery Mode[/b] — Unlock CGs, replay key story moments, collect every encounter.

[*][b]💬 "Survivalist" Inner Monologue[/b] — A protagonist who stays analytically calm amid total chaos. Entertainment guaranteed.

[/list]

[h1]🍑 About the Title[/h1]

[b]28 Days[/b] — the deadline Xiao Ming's sister gave him.

[b]Half-Life[/b] — the decay cycle of the fungal samples.

It's also the average shelf life of dignity, rationality, and survival instinct in this generation of university students.

[h1]💭 You'll love this game if you enjoy:[/h1]

[list]

[*]Daily slice-of-life blended with otherworldly fantasy

[*]A protagonist who actually has a brain (and keeps a ledger)

[*]A cast of women, each with their own secrets

[*]Stories where "dating" is the surface, but science is the core

[*]Clever dialogue that makes you want to screenshot everything

[/list]

Welcome to Wujiang University.
