In the game, there are not only the links of searching for clues and reasoning passwords that can be done by the lower chamber of secrets, but also the clever organs that are not easy to do but can be easily realized by the engine and code. The secret room consists of two scenes, namely, the home room and the school dormitory. Players will be trapped in the furniture room at first.

This game is a virtual reality game, it is recommended to experience the immersive feeling in the case of wearing VR equipment. In the absence of VR experience equipment, it can also be experienced as an ordinary computer game. Synopsis: The protagonist (played by the player) is a married woman. The love between her and her husband fades and disappears, and the marriage is full of cracks. One day, she suddenly finds herself trapped in the living room of her home! After being shocked, she vaguely felt that something was wrong. After observing left and right, she found that there seemed to be many different places in the familiar living room. Strange TV screens, movie tickets scattered all over the place, disappeared pet dogs... Facing the unlocked door, she must rely on her own wisdom to find out the password. But unexpectedly, after successfully leaving the living room, what she faced was not the corridor of the building, but a narrow path. At the end of the path was a strange and familiar iron gate... She pushed open the iron gate and found that it was her dormitory in college! However, the door that could be opened just now suddenly locked again. In the face of the college days that have long been submerged in time, she looked at scattered books, simple desks, and weird password boxes, little by little to find the best and purest past that she had forgotten. Finally, she opened the last lock and took out a letter from the password box that she wrote to herself now. Looking at the sunny and confident ideals in the letter, she finally found the light to move forward. "Yesterday's future" represents the two meanings, today is the future of yesterday, today is also the future of yesterday. If we feel confused and painful today, we might as well go back to the past to find our original intention and seek a bright future that does not forget our original intention. We hope to tell everyone through this story that no matter when, we have the right and ability to find our own heart. It may be a difficult process, but when you hold the moment of your first heart, at least at that moment you will feel that life is full of hope.
