Another possible theme could be the acceptance of fate. If the story involves Thanatos, the characters may have to come to terms with their own mortality or the mortality of their loved ones. And love could be the driving force that helps them in this acceptance, guiding them through the difficult journey of understanding and living with their fates.
One possible plotline could be that Thanatos, who is often seen as a cold and efficient agent of death, starts to question his role when he meets Death in a more personal way. He begins to feel emotions he's never experienced before and they fall in love. Another could be that they are both lonely in their existence as figures associated with the end of life and find solace in each other. They might then face challenges from other underworld entities who are not happy with their new - found relationship.
One common theme is sacrifice. In many such stories, one or both of the lovers sacrifice something major, often related to their own life or well - being, for the sake of the love. For example, in some vampire - human love stories, the human might sacrifice their normal life to be with the vampire.
There isn't really a classic 'Thanatos and Death love story' in the most common understanding of Greek mythology. But if we were to create one, it could be that Thanatos, who is often depicted as a rather solitary figure in his task of taking lives, meets Death in a more personified form. They might start to understand each other on a deeper level as they both deal with the same fundamental aspect of existence. Their love could grow out of a mutual respect for their roles, and they would become a sort of power couple in the realm of the afterlife, with Thanatos handling the physical act of taking souls and Death being more of the overarching concept that he serves.
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.
One possible theme could be sacrifice. Given the historical context of 1917 which might involve war or social upheaval, the lovers may have to sacrifice their own desires for the greater good or for each other.
