Can you recommend a European novel where the protagonist remains optimistic and confident in the face of adversity?

It mainly reflects the protagonist's optimism, but it can't be extreme. After reading it, I feel that it is similar to the optimistic attitude of a person in real life. I want to use it at the beginning of my personal statement. Thank you. If it is good, I will add it again.
The protagonist doesn't need to experience particularly miserable suffering. The whole story gives people the strength and beauty of a woman. It doesn't need to be too grand.

The book "Master of the Heart" was a game novel written by the author, Jun Buwo, Mo Jizhi. The general plot of this novel was:

This was a good era of peace. Steam engines and airships brought convenience to life. Ocean-going giant ships expanded new colonies. White churches guided people to good. This was a chaotic bad era. Money was supreme and extravagant life corrupted people's souls. Saints were forgotten, and evil lurked in the dark side of the city, waiting for an opportunity. The reason why we live happily is not because of peace, but because of the nameless people who hide their faces and bow their heads to protect us silently. When the twisted evil descended upon the world, and the rights that were once taken for granted became privileges, would you still remember those who carried the burden? As an observer, I will record a person named Lorne. Wellington's unlucky transmigrator, I will record in detail his short but comedic legendary journey. His hesitation, joy, happiness, grief, anger, redemption…will be remembered by me. The audience who read this might think that Lorne was a hero, a coward, a miser who insisted on asking for money, or an awkward guy who did not mean what he said... But please remember, he was originally just like you and me, just an ordinary person who worked hard to pursue happiness.

"The Day of Survival in a Foreign Land" was a sci-fi novel written by Auon. The general plot of the novel was:

When he started writing this novel, he had thought about many things. The unknown energy radiation on Earth's blue planet caused a large number of creatures to undergo abnormal evolution. The climate and magnetic field were chaotic, and humans were facing extinction. The protagonist who survived in the disaster area was cold on the outside but warm on the inside. From survival to escape, he met one reliable companion after another and finally established his own family. Together with all mankind, he found an opportunity to win in this craze of evolution. Although this book is defined as a science fiction apocalyptic novel, I think the atmosphere created is positive. The original intention of the creation is to hope that through the protagonist's growth bit by bit, he will overcome setbacks and difficulties, not give up his initial dreams and beliefs, and finally win the future. It will encourage the readers who read this book to gain the courage to continue moving forward, even if it is only a little. A happy ending might be too ideal, and reality was always cruel, but it was precisely because of this delusion that we would chase after it regardless of everything.
