My name is Xiao Mang. After graduating from undergraduate, I went to the United States to study as the first in the chemistry department. I was admitted directly with a doctorate. Although the school is not in the prosperous city, the strength of the college and the boss's team are famous for a year. My girlfriend Xiaoxue, who has been in love for four years, also came to the United States to study for a master's degree. The school is less than 50 kilometers away from me. At that time, I was full of expectations. She concealed her itinerary from me who was about to pick me up. As soon as I landed, she called to break up. I didn't even see each other once. I couldn't suffer for a long time. The new crown epidemic that changed the world spread in the United States. The team's research projects were delayed. Even the school dormitory could not be able to live in the school dormitory. Taking advantage of the down payment, I quickly asked my parents to buy a small apartment. Although it was only two bedrooms, one living room and one bathroom, it was a place to stay.
