My hypothesis is that, Hwisoo was aware of his sexual orientation but he couldn't accept it due to some circumstances or traumatic experience perhaps, so he forced himself to be a straight man. And when he decided to get married, that's when his alter ego (Yushin) immerged. It's like Yushin expressing Hwisoo's genuine desires. Then again, this is just a. hypothesis base on what I've read so far.
