About Our Brief Eternity
Our Brief Eternity is a story about an ordinary person, Lin Xiaocou, who finds his peaceful life changed when a vampire and a witch accidentally enter his home. As they live together, they share everyday moments such as shopping, playing games and talking about secrets late at night. Their lives grow closer, even as they confront the reality of their different lifespans and the pressures of ordinary life.
The people at home
The vampire is an elegant aristocrat who has lived for more than 300 years. Tired of life in her old castle, she ran away from home and found Lin Xiaocou’s house, which she considers a suitable temporary base. Proud, sharp-tongued and reluctant to deal with trouble, she teases Lin Xiaocou and makes requests that are not difficult, but are troublesome. Beneath her haughty manner, she is warm-hearted and finds comfort in his company; their daily life also makes her curious about the fleeting nature of human life.
The witch is more than 100 years old and stopped aging after a magical accident. Lively, curious and clumsy, she often causes minor mishaps and tries to solve problems with magic. She travelled alone after studying under a great witch, then arrived at Lin Xiaocou’s home in a teleportation accident. After tasting the desserts in his refrigerator, she decided to move in. Behind her cheerful manner are a sensitive nature and a sadness she rarely shows; she feels at ease with Lin Xiaocou and gradually learns to express herself.
