really love the ost. i m a solid yaojing fan but i sincerely appreciate ffb/xl and xy cp too. there is a element of love and hate with xl and more to sad because he can never meant to be. xl will always be against CX no matter what. she cannot tolerate ppl who harm CX. with FFB it is like she has lots of fun with him. she is really relaxed with FFB. and i love their ost the most. sound so sad and melancholic. walking in snow till the end by himself. ouch.
Put it this way, if XY is our daughter who do you think is the best of her. TBH with Jing unbreakable betrothal, in modern terms, he is engaged with someone else and yet keep coming to look for your girl, if i am Mum i will not really trust Jing as well in real life, so CX portrayal as a worried brother is not really wrong or uncall for. XL a bit too evil and FFB too playboy. And i don want my daughter to marry a man who is going to have a big responsibility like CX too. oh well, stay with mommy. i will look after a cutie like XY.
