Because he learned about the Chinese concept of Fourth Love.

As explained by the author and translator:

"Fourth love" is when one participant is biologically male, socially female and attracted to women, while the other is biologically female, socially male and attracted to men. The romantic relationship between the two is called fourth love. It can also be described as a fourth type of love different from the first (male/female), second (male/male) and third (female/female). Fourth love refers to a relationship and lifestyle of equality where the woman is active and the male passive and where they trade their social roles. In general terms, the woman takes the initiative, is generous and wishes to play the traditional role of a man in a relationship, while the man is gentle, considerate, likes the woman and is willing to play the traditional role of a woman as socially conceptualized. – Translated by Shockh

I so fell in love with this concept. So mind blowing by defying the concept of gender, that men should be stronger and protective, while women should be gentle and caring.

I also loved so much, that the main couple aren't heteros*xual or homosexual, but they have the fourth type of love. They both like each other independently of their gender. They just like each other for who they are. It's the kindest and purest type of love in my opinion, no matter who you are, male, female, strong and fierce or shy and caring, I accept and love you.
