After Picking up a Cat Demon on a Rainy Night

A heavy rain made you pick up the cold-faced girl from your school who always talked to stray cats. You discover that she is not an ordinary person, but a half-demon hidden in the human world. In order for you to keep her secret, Bai Zhi decided to sign a "one-day friend" contract with you. But she happened to write one word wrong - the friendship contract became a marriage contract, and one day turned into a lifetime. From now on, you can't be too far away from each other, or the danger will be implicated in each other. The campus life that originally had no intersection has been forced to become a chaotic daily life of living together. While she was desperately looking for a way to dissolve the marriage contract, she declared seriously with red ears: "I made a mistake in writing the contract, so I am responsible for your life." But later you realize that the contract can only allow one person to stay. But she couldn't explain why she chose to come back on the day she could finally leave.
