The Traveler in Time and Space Painting is a plot love mobile game based on the world view of the concept of "parallel time and space". Ain is a painter, a person who has the ability to travel through time and space and travel in different parallel worlds. Players play the role of freshmen in the art department who have just entered the university. On the one hand, it is the warm campus daily life in the real world, on the other hand, it is inadvertently involved in the doomsday crisis in a different world. Parallel time and space, similar faces, different personalities. This proposition about "love and redemption" is waiting for players to draw their own choices with drawing strokes. Ain's situation in the game is very abusive

Ain and Lu Chen are both players of Time Traveler.
