The love between them started from not understanding each other and sharing weal and woe.
From immature to mature.
Even though he is a divine king, he still has shortcomings, and she is also immature. Even though they are gods, they are just like mortals, with realities and destiny that they cannot escape. But they and their love grew up together.
For him, she grew up step by step to be able to stand beside him, and he was always not far away to protect her. Wait for her.
Their love makes them both become better people, and they become mutually supportive.
Good love is when two people grow together with love.
Good love is one that persists even in the face of destiny.
Good love means that I strive to grow up to be comparable to you, and you don't just pamper me blindly, but let me learn to protect myself, learn to love others, and teach me how to not get hurt.
Good love means that when we have each other, we can get rid of those bad habits.
All cause and effect is nothing but fate. Believe in it for a lifetime and carry it with you forever.
