Yin and yang energy in Asian culture is typically summarized as such: yang energy is masculine and yin energy is feminine. To gain more yin energy you could take/perform certain things to achieve it such as eating stuff with lots of yin energy or having sex with a woman/someone with a lot of yin energy. The Blondie needed yin energy to remain as a spirit while in a coma, and the mc needed yang energy to drive off the spirits.
In chap 2, seme said that if uke doesn't reduce the amount of yin energy he has, he'll attract more spirits which will in turn make him fall gravely ill. And now, since the uke can't use dream sex with as a way to reduce yin energy bcs seme isn't a spirit anymore, how is he supposed to keep it under control? Will uke get sick in the side stories or something?
