Interstellar Kindergarten transferred a new student named Xixi from Mars.
The new children were a little shy, so the teacher asked local child Lang Lang to take the new children to familiarize themselves with the surrounding environment.
The children played games together, told Xixi the story of the earth, learned about the mysteries of the earth, and discovered the magical phenomena in life.
They became the closest of friends, a friendship that spanned interstellar light-years.
