No matter if it's Shuiyue and Jinghua, or Bai Hui and the three Gu sisters, Luo Yang cannot easily let them bear his children.
Having a relationship with them is already troublesome enough.
If they give him babies, then for the rest of his life, Luo Yang would have to deal with beatings and killings.
Walking by the lake often, how can one not get their feet wet?
If he gets involved just once, he might have to go have afternoon tea with King Yanluo.
Luo Yang only wants to quietly develop into the world's richest man, then plant flowers with beauties, dance, drink, travel during leisure times, and exercise for health and wellness with beauties during busy times.
This is the life Luo Yang pursues.
Therefore, the life philosophies of Luo Yang and beauties like Shuiyue, Jinghua, Bai Hui, and the three Gu sisters are worlds apart; they are fundamentally not the same type of people.
Unknowingly, he ended up marrying them.
