The door that could not be opened

Yu Pan, the receptionist has said prayed that she wanted to get engaged and Song Yan waited for the latter to get engaged, for three days consecutively she sent Fang Yanli to monitor that woman whether or not she was proposed to by her boyfriend and after waiting for four days and three nights she was finally able to get the 'good news' from Fang Yanli who told her that the woman has indeed gotten engaged to her boyfriend. 

" You are here," Fang Yanli raised her head as she turned to look at Song Yan who was walking towards her while dressed in a black trench coat with completely black attire. 

Song Yan nodded and asked whether or not Fang Yanli has seen Yu Pan who walked past this street every night.
