One possible theme could be acceptance. Since yetis are not the most common or understood creatures, the story might be about the yeti finding someone who accepts it for who it is. Another theme could be transformation. Love often changes people, and for a yeti, it could mean becoming more gentle or outgoing.
There could be a theme of discovery. The yeti discovers love, which is something completely new to it. It could also be a theme of breaking boundaries. A yeti falling in love with a different kind of being would break the normal boundaries of its species' behavior. And perhaps a theme of courage as well, as it takes courage for the yeti to pursue love in a world that may not be ready for such a relationship.
It might involve a yeti finding love with a human in a remote and magical place. Maybe they overcome prejudices and differences to be together.
Since I'm not familiar with 'A Yeti Love Story', I can't say for sure who the main characters are. But it's likely that the yeti itself is one of the main characters. There might also be other characters like animals or other mythical creatures that interact with the yeti in the context of this love story.
Since I don't know the exact 'Yeti Love Story', it could be the yeti itself as one of the main characters. And perhaps another yeti if it's a love story within the yeti community, or it could be a human or some other magical creature.
I'm not sure about the specific 'Yeti Love Story' you mentioned. It could be about a yeti finding love in the cold and snowy environment, perhaps with another yeti or a different creature that ventures into its territory.
A third theme might be the pursuit of dreams. If one or both of the lovers had big dreams, like traveling the world or becoming an artist, their love would be intertwined with their individual pursuits. They might have to choose between love and their dreams or find a way to make both work in the context of their relationship.
One possible theme could be sacrifice. In 1941, during the war, lovers might have to sacrifice their time together, or one might sacrifice their safety for the other. Another theme could be hope. Despite the dark times of war, their love could be a source of hope for a better future.
One possible theme could be nostalgia. Since it's related to 1989, it might evoke a sense of longing for the past, especially for the time when the love story took place.
In a 2023 love story, the theme of second chances might be present. Maybe someone had a bad breakup in the past and in 2023, they meet someone new who gives them a chance to love again. Technology can also be a theme. People might have met through a dating app in 2023 and their relationship developed from there. And of course, the theme of family could be there. A couple in 2023 might be building a relationship with an eye towards starting a family in the future, so they are learning to support and care for each other like a family unit.
One possible theme could be social change. In 1950, society was evolving, and a love story might have been influenced by new social norms. Another theme could be sacrifice. The lovers may have had to sacrifice personal desires for each other or for their families.
Another theme could be hope. People in 1948 were looking forward to a better future after the destruction of the war. So the love between two people could represent the hope for a new start, both in their personal lives and in the broader context of the world around them. It could also be about the theme of change. 1948 was a year of significant change, and the love story could revolve around how the characters adapt to the new social, political and economic changes while falling in love.
