[The Journey of Flower] I Hate Bai Zihua Most of All!

Uh... can someone tell me why Hua Qiangu is a guy? I mean, doesn't Hua Qiangu like Bai Zihua? Aren't they supposed to be locked in a love-hate relationship? Have relationships between men already become popular at this point in history? The ancients were so open-minded... Heh! So did it go something like this? Hua Qiangu was a man, but then he met Bai Zihua and slowly fell for Little Bai Bai (Bai Zihua). Then, through a series of twists and turns, by some strange coincidence, and after swearing eternal love, he used Martial Universe (what even is that?) to hide his gender. Then he met Killua Jie and they talked about how to become more feminine, so they became best buddies. After that, he and Little Bai Bai had their love-hate relationship, until at last Hua Qiangu said, "I'm actually a man. Don't you think that's disgusting?" Little Bai Bai said, "No, I... actually knew. I was just afraid you wouldn't accept me..."
