My name is Yan Fei, a hard-working female doctor who is not good at words and has no hobbies. Now I am interning in a laboratory of a research institute. In the tall and majestic building, everyone is busy coming in and out. If it is not for work, there is almost no communication. The fast-paced work life often makes me feel stressed. Dong Qi, my boyfriend, we have been in love for 9 years. From the same undergraduate major, to the same college for master's degree, to the same city for PhD, we have been noisy all the way. Finally, we decided to get married this year, and the wedding date will be next month. I went to the mall to buy a pair of wedding shoes and started a nightmare journey. Shoes represent a person's personality and even their profession, and a weird hotel collector collects all kinds of shoes. I entered the hotel by mistake and escaped after all the troubles. I thought I had escaped, but in fact the nightmare had just begun.
