Secret love and being secretly loved are two different individuals, one is deeply hidden in the heart and the other is completely unaware. Su Mo had a crush on Tang Lekang when she was in college, but she didn't know that she was also secretly in love with her. When he was creating "accidental encounters" with Tang Lekang again and again, how could he think that one day, he would "encounter" the same person again and again.
Probably every secret admirer is a master at creating "accidental encounters".
