In this interstellar world, where females are scarce and males are plentiful, Lin Zhiyu (heroine: 186 cm, 25) marries Duke Su Yanci (hero: 196 cm, 29), the powerful ruler of the empire.
These two poor souls comfort each other, and their marriage turns into love. (Except Su Yanci, who falls in love before they marry.)
The male lead has a snake-like vibe, with a calculating personality and a jealous streak.
The female lead has a cat-like vibe: cool and aloof, adorably deadpan, and fond of sleeping.
You can meet the other characters later.
(The heroine is wholeheartedly supported. The heroine is wholeheartedly supported. The heroine is wholeheartedly supported.)
It's good-looking, has double A, and the heroine is so strong.
