Review of Rainbow Eyes

This film had me guessing all the way thru excellent done actor's are amazing I would call this a bisexual film instead of a gay one still worth the watch It did raise a couple of questions for me.which I don't want to give any thing away so I can not really express it here

But I have watched a lot of k-Drama's were the actress pretends to be a guy fooling all the guy's and then one of the guys falls in love with her thinking the entire time she is a he only at the end It is revealed the truth,but to me that guy is bi what do you think and If you have seen this movie do you think Jo Kyeong-yoon is gay or bi ?
