Overcoming obstacles. There are always various barriers in the path of love in these novels. It could be family disapproval, as in 'Romeo and Juliet', or differences in social class. But the characters strive to overcome these for the sake of their love.
Growth. Love often makes the characters grow as individuals. They become more understanding, patient and empathetic. In a 'for the sake of love novel', the journey of love is also a journey of personal development for the protagonists.
One common theme is friendship. Sake is often used as a way to bring characters together and strengthen their bonds, like Naruto and his friends sharing a drink. Another theme is tradition. Sake has a long - standing tradition in Japanese culture, and in Naruto fanfiction, it can represent the ninja traditions.
In the context of the novel, 'love for love's sake' might imply a pure and selfless form of love. It could mean that the characters are in love simply for the essence and beauty of love itself, without any ulterior motives like wealth or status.
One common theme could be sacrifice. Characters often sacrifice their own desires or opportunities for the sake of their loved ones. For example, they might give up a career opportunity in a far - off place to stay with their partner.
The theme of time can also be important. Long separations due to various reasons can interrupt love. For instance, in some novels, a character may have to go to war or on a long journey. During this time, their love is put on hold. Also, the theme of redemption can be present. If love has been interrupted due to a wrong - doing, a character may seek redemption to restore the love.
One common theme is social class differences. For example, in 'Romeo and Juliet', the Montagues and the Capulets' feud, which is related to their social standings, makes their love seem impossible at first. Another theme could be cultural or religious differences. If a novel features a love story between two people from different religions that have strict rules against inter - faith relationships, it creates an impossible love situation. Also, fate often plays a role. Sometimes the stars seem to be against the lovers, like in some tragic love stories where external events keep pulling the lovers apart no matter how much they love each other.
Power dynamics can also be a theme. There could be an unequal distribution of power between the characters involved in the love 'trap'. One might have more control over the relationship, either because of their social standing, knowledge or some other factor, which leads to a complex web of interactions.
Another theme is the fear of rejection. Since it's a secret love, the characters are often afraid that if they reveal their feelings, they will be rejected. This fear drives a lot of the internal conflict in these novels.
One common theme could be unrequited love. The protagonist may love someone who doesn't return the feelings. Another theme might be love that is forced or arranged against one's will. For example, in some stories, a character is pushed into a relationship they don't want.
The theme of longing and anticipation is also frequently seen. Lovers in love novels often long for each other's company, wait for each other through hardships, like in 'Wuthering Heights' where Heathcliff and Catherine have a complex and passionate love filled with longing.
Common themes in the course of love novels include first love. It's often depicted as pure and intense. Then there's the theme of unrequited love, which brings out a lot of emotions such as longing and heartbreak. Another one is the theme of love at first sight. It sets the story in motion quickly. Love novels also often deal with the theme of loyalty in love, showing how characters stay true to their loved ones despite temptations.
