Do you have any recommendations for interstellar novels about the childhood sweethearts of the male and female leads? I forgot its name.

The male and female leads had been engaged since they were young. They must like each other, right? When he grew up, the male protagonist felt that he hated the female protagonist. Coincidentally, the female protagonist eloped with a male liar and fled to another planet. The male protagonist took advantage of this opportunity to grasp the real power of the alliance. Later, the female protagonist met the second male protagonist. The second male protagonist was the male protagonist's opponent and the leader of another planet. He deliberately approached the female protagonist because the female protagonist was once the male protagonist's fiancée. Later, the war broke out and the female protagonist was injured and dying. The second male protagonist sent the female protagonist back to the male protagonist, but he planted a time bomb in the female protagonist's body. The female protagonist woke up and told the male protagonist that she had a bomb on her, so she asked the male protagonist to throw her out. The male protagonist threw her out, and the female protagonist's body exploded into pieces. The male protagonist never married and died at the hands of a female spy who looked like the female protagonist. I've been looking for this article for a long time. I forgot its name and can't forget it.
After the war and peace, the male protagonist reached a peace agreement on the planet. After ruling for a long time, he didn't want to live anymore, so he was killed by the female spy without resistance.
