[Transmigrate into a book + transmigrate as herself + pocket dimension + feel-good story]
Meng Chujun wakes up to find she has transmigrated to the 1970s, and the little house in the countryside has come along as a pocket dimension. Everything inside replenishes as soon as it’s used, and the place even comes with a lake of life-saving water!
When Liang Yanyue wakes up, she discovers that all her friends are missing. Luckily, she gets a navigation System that can precisely locate people she knows who are still alive, and sets out to find her friends.
Wen He and Li Zi open their eyes and find each other, but they can’t locate their other two roommates. With a breakfast shop and a mall that refresh every morning at dawn but won’t let anyone enter, they begin a comfortable life in the Northeast, unaware that their other two friends are already on their way to find them...
Meng Chujun is the main viewpoint character, so she gets more of the story, but the other three get plenty of scenes too. None of the four have romantic pairings, though there are plenty of one-sided crushes.
