Ye Fei's favorite woman has always been Liu Yiru, both spiritually and physically.
Spiritually, it goes without saying. She is Ye Fei's biological mother and the epitome of perfection in his eyes.
Ye Fei's feelings for her extend beyond love to the natural attachment a son has for his mother. This kind of affection transcends romantic love.
All the women in his life understand this, so no one thinks it's inappropriate or gets jealous that Ye Fei loves Liu Yiru the most.
Physically, it's even more evident.
Liu Yiru's beauty and sex appeal are already top-notch. With Ye Fei's excessive pampering, she is undoubtedly the most beautiful woman in the world, having reached the pinnacle of human beauty.
More importantly, she is Ye Fei's biological mother. The thrill of having his dick inside his own mother's cunt is something Ye Fei finds irresistibly addictive.
