I'm confused about something. ML apparently fell in love with FL while they were in HS but he thought she was…
Yes. Basically Yan Ke(ML) started to get attracted by the personality of Xiong Yifan(FL) in High school; He started to like Her but was still in puzzled situation that "Does He really like a boy?"....and also he didn't know her real name(He thought her name was Qi Xiao Song, which was a name of boy)He had a confusion that whether he was really in boys or not!!But he had a strong sense of getting a friend like Xiong Yifan,who was trustful, and to be relied on.....But actually Yan Ke(ML) got misleaded by the TOMBOISH nature of Xiong Yifan(FL).
