What do you mean it's hard to raise a girl?

From this life, I asked how to run in the future difficulties. It is difficult for men and women to raise, and it is difficult to raise their own flesh and blood.

Literally. Don't worry about the difficulty of having children, it's not accurate. Even if you believe in fate, you don't have to believe this. The numerology is complicated, and there are many factors other than the eight characters.
