The title implies that love is the binding factor. So possible themes could be the different forms of love, like self - love which might be shown as a character learning to love themselves before loving others in one of the stories. Another could be unrequited love and how characters deal with it in the four stories. And of course, the idea of love as a unifying force between different individuals or groups could also be a theme.
One major theme is probably redemption. In Christian fiction, often characters are on a journey of being redeemed, whether it's from sin or difficult circumstances. Another theme could be grace. Just as God shows grace to us, characters may experience grace in the stories. And love is central, binding the characters and the different stories together, much like how love is central in Christian teachings.
Unity could also be a theme. Despite the differences represented by the four colors, they come together to form a complete love story. It's like the different elements in a relationship - passion, loyalty, friendship, and growth - all combine to create a harmonious and fulfilling love experience.
I don't have enough information about 'bound by love four stories'. It might be a collection of tales centered around the concept of love that binds characters or situations together. But this is just speculation without further details.
One possible theme could be simplicity. Amish families live simply, so the stories might show how they value basic things in life.
One possible plot could be that the two lovers are in a dangerous situation where they are bound and gagged by some villains. But their love for each other gives them the strength to endure and eventually find a way to escape and be together.
Duty and loyalty. These are closely related to honour. The characters usually have a strong sense of duty towards something or someone, and their loyalty is tested in the face of love. It could be loyalty to a kingdom or a group while being in love with someone from the 'opposite side'.
Another theme could be self - discovery. When a wife is in a bound situation, she often has to look deep within herself to find solutions. She might discover new aspects of her personality, like her courage or her intelligence, as she tries to deal with the binding circumstances.
Another theme is the breaking of family restrictions. In Chinese family - centered society, family often has a say in one's marriage. But in these novels, characters' love might go against their family's wishes. Their love is so strong that it doesn't care about the family boundaries and traditions that try to confine it. This shows the power of love over family - imposed limitations.
Another theme is the cat - and - mouse game between the robbers and the authorities. This creates a lot of suspense. For example, in detective stories where a robbery has occurred, the detective has to use his wits to catch the thieves while the robbers try to evade capture. It often involves a lot of clever hiding of evidence and false leads.
One main theme could be the struggle for freedom as the 'bound man' in the title might suggest some form of confinement. Another could be human relationships, as stories often explore how characters interact with one another.
