Rebirth and Struggle: a Bright Life in Space

I really can't stand it anymore, why do you keep talking about the heroine's sister? And why does the male protagonist keep helping the female protagonist's sister, knowing that she loves him. It's better for them to fight each other, but it makes me sick. He also said that if the heroine's sister wasn't so pampered, she would be his wife. So disgusting. I really don't understand why the heroine would marry such a man. Isn't it good to be beautiful alone? Moreover, the author does not distinguish between priorities, the male and female protagonists have so few roles, and the constant talk about what the female protagonist's sister is doing makes me sick.

She has returned from the apocalypse, and the halo of the heroine, the Virgin, is so dazzling

The heroine is still a person in the last days, and the Holy Mother must be like the savior who saves the world. The male protagonist calls another woman's name more affectionately than his own wife's name
