You were always two. You and your twin. Your twin is the goddess of the Sun and you, the god of the Moon.

When the god of the Gravity, Chuuya, asked her to marry her, you didn't want to let her goes with a person that she doesn't love (she loves the god of War). Then, you proposed to be his husband.

He accepted, but seems annoyed by your proposal

You are in your room, after the marriage. And Chuuya doesn't seem happy...
