梨花落尽，云散夜未明

Materials research at the institute is done in groups under a senior member, and Xie Yunchi leads the one Shen Wanli is in. She has been in love with him for ten years. She turned down a position at the top of the field to stay on as his assistant, and she was badly hurt getting him out of danger. After a kidnapping, Xie Yunchi proposed out of guilt and they were engaged. Then she watched what he let Ye Xi, a junior in the group, get away with. Her core result was signed over to Ye Xi. In front of a room of people she was described as the assistant who does the odd jobs. She sold the flat bought for the wedding, called the wedding off, cut every line of contact, and took the posting she had been offered at the Northwest Aerospace Research Institute. Some time later he came looking for her and asked her to come back.
