Well, she obviously got a little disappointed after he confirmed that he was gay. The soft rejection is a real possibility.
I can't really blame her. Who wouldn't fall in love with YuYang? Straight or gay, he is a wonderful person. He is so caring and even keeps a record of your period :D
I don't think she is the stalker type either. She just probably likes his company.
In my opinion neither.
For those of you who read 'Guang Xiang', YuYang already knew that Lin Xiang is in love with Xiao Guang. When they were on the roof top, he even told him to go for it. He told him not to care about what society thinks and be happy. So ever since the confession the two guys have been together. Since YuYang and Lin Xiang go to the same school I'm sure he knows about it. That they are officially a couple and they are happy.
Regarding Chu HuanWen, I know he keeps inviting him to the gay bar, but he knows he is straight.
So... I can't imagine him desperately clinging to someone who is in a relationship. Maybe hoping one day they would break up. Or flirting with someone who is clearly not gay.
