Self - growth within the context of a relationship is often seen. As the characters fall in love, they also learn more about themselves, their desires and their capabilities. In some novels, the love story serves as a catalyst for the characters to become better versions of themselves.
Overcoming obstacles is also likely to be a theme. For example, differences in social class, family opposition or personal insecurities that the lovers have to get past to be together.

When two people are not supposed to be together due to social or family reasons but still fall in love.

Love and sacrifice are very common. In many romance short stories, like 'The Gift of the Magi', the characters give up something valuable for the sake of their love. Another theme is unrequited love. For example, in some stories, one character loves another who may not feel the same way. Longing and separation can also be themes, where the characters are apart but still deeply in love, such as in some war - time set romance short stories.
The theme of love conquering all is also prevalent. In stories, love can bridge differences in social class, overcome family objections, and even survive great hardships. For example, in some fairytale - like short stories, love between a prince and a commoner can triumph over all obstacles.

Another theme is the idea of a soulmate. Werewolf romance stories often depict the concept that there is one special person out there for the werewolf, usually their fated mate. This is a very romantic idea and drives a lot of the plot in these stories.
Another theme is death and the afterlife. Dark romance often involves the idea of losing a loved one to death and the character's struggle to come to terms with it or their attempts to be reunited in some way. It can also include the idea of loving someone who is already dead or a supernatural being related to death, like a ghost or a reaper.
Love against all odds is also a theme. Society may not always be accepting of same - sex relationships, so characters often have to face challenges. In 'Call Me By Your Name', the two main characters have to deal with the fact that their relationship might not be fully understood or accepted by those around them.
Sacrifice is also a key theme. Characters might sacrifice their own happiness, dreams or even their lives for the sake of their loved one. This selfless act, while noble, often has a sad undertone as it can lead to personal loss or unfulfilled desires.
