Become an ally, Wen Qian and Bai Jiran have a relationship. They are in the same room in the hostel, one bed and one floor bunk. Bai Jiran looks at the sleeping Wen Qian and falls into the memory. He takes out the lipstick he bought from her pocket. Suddenly turned over and fell off the bed, the wakefulness of the light and shallow can not help but say Bai Jiran, thinking he was going to play hooligan to himself. The lipstick sent by Bai Jiran is very special in Wen Qian’s heart. Wen Qian believes that this lipstick is the key object connecting two people. Early the next morning, the two arrived at the station from the Youth Hostel and left Chengdu according to Wen Lin’s new email instructions.
