Osta Our Brief Eternity PC

"In this world, there are things you shouldn't do, yet you can, and things you can do, yet you shouldn't."

When an elegant vampire and a clumsy witch suddenly burst into your peaceful life, how will you, an ordinary person, get along with them?
During this brief but precious time living together, you will share a life full of joy, fun, and unexpected moments.
Whether it's going out shopping, playing games together, or sharing heartfelt secrets late at night, every moment quietly brings you closer.
You gradually come to understand each other—life paths that seemed completely different now intertwine because of this accidental meeting.
You experience the warmth of a home, but you must also face the trials of differing lifespans and the pressures of reality.
Every choice you make will affect the story's development, leading to one of four distinctly different endings.

Will you risk accepting an eternal life to become their companion?
Or will you cherish the present, guarding the promises you made to each other in this fleeting time?
The decision is all yours.

"Hmph, it's not like I decided to stay in the human world specifically for you!"

An aristocratic vampire who accidentally breaks into the protagonist Lin Xiaocou's home. She appears elegant and proud, but is actually a homebody who despises troublesome things.

With a proud and sharp-tongued personality, she often bluntly points out Lin Xiaocou's predicaments, teases him from time to time, and makes various "not difficult, but very troublesome" requests. In reality, she's cold on the outside but warm on the inside and isn't good at expressing her true feelings, using a haughty attitude to hide her inner turmoil. She enjoys the feeling of being with Lin Xiaocou and is most relaxed and at ease when they are together.

As a vampire who has lived for over three hundred years, she grew tired of the unchanging life in her old castle. After running away from home, she stumbled upon Lin Xiaocou's house, seeing it as a "decent temporary base." Although she always acts like a bystander, through their daily interactions, she gradually becomes curious and fond of the fleeting nature of human life.

Personality: Lively and clumsy, full of curiosity, sensitive and delicate.

"...I'm not an idiot. I just don't want to face a reality that is too cruel."

A witch who accidentally breaks into Lin Xiaocou's home. A magical accident caused her to stop aging.

She has a cheerful and lively personality, yet she is clumsy and prone to causing trouble. Beneath her innocent and naive exterior lies a sensitivity that far exceeds her appearance and a hint of imperceptible sorrow. She is accustomed to solving problems with dazzling magic and hiding her inner anxiety with a smile.

Full of curiosity about the world, she firmly believes that "fun" is the ultimate creed in life. She can become vulnerable when her emotions are unstable but will occasionally show a more passionate side. She feels at ease by Lin Xiaocou's side and gradually learns to express her true self.

After studying under a great witch for many years, she began to travel alone once she could stand on her own. She stumbled into Lin Xiaocou's house during a teleportation accident and, after tasting the desserts in his refrigerator, decided to move in without a second thought. Although she always causes minor mishaps, she consistently tries her best to blend into human life.
