This Is Peace, This Is Peace, These Female Twins

Two girls, one is as beautiful as the sun, and the other is like a firefly in the night. They met two different men, each sweet and struggling, falling in love at the same time and making the same difficult decision. The change of day and night is restricted by the laws of nature or the contract between man and God. If the rules are broken and the contract is terminated, will the sun cover up the night or the night will stop the sun? How should two girls choose, who their hearts belong to, and where their souls belong.
