Another possible theme is acceptance. Accepting one's own imperfections and those of others is often a key part of stories. In 'Imperfect Heart Novel', the characters may need to accept their imperfect hearts and the situations that come with them in order to move forward in their lives.
Love could be one of the main themes. Imperfect hearts often struggle with love, whether it's finding it, keeping it, or dealing with the pain it can bring.
Self - acceptance is likely a main theme. If it's about an imperfect girl, she probably has to come to terms with her own flaws.
Overcoming insecurities could be another theme. The imperfect girl in the manga probably has to deal with insecurities related to her imperfections, and the story would show how she battles them.
The main theme might be about the various imperfections that women face in society and how they navigate through life with those. It could also explore the concept of female identity in the face of such imperfections.
In an imperfect life story, the theme of change is quite prevalent. Life is constantly changing, and not always in the way we expect. There are also themes related to regret and forgiveness. People may have things they regret, but learning to forgive themselves and others is part of dealing with an imperfect life. And of course, the theme of hope always persists, no matter how difficult the situation is, there is always hope for a better future.
Perhaps the theme of sacrifice is present in 'the heart novel'. Characters may have to give up something they cherish, like a dream or a relationship, for a greater good. And social inequality might be another theme, showing how different characters are affected by the social structure in the story.
Since I'm not familiar with the 'Imperfect Girl 3 Novel', I can only speculate. The main character is most likely the imperfect girl. She may be surrounded by a diverse group of characters. There could be a strict parent who has high expectations of her and thus highlights her imperfections more. Or a kind neighbor who offers her a different perspective on her so - called flaws. And of course, there could be a love interest who sees beyond her imperfections and loves her for who she really is.
I'm not sure without reading the book, but they are probably women who are dealing with different types of imperfections.
One of the main themes could be love and loss. The broken heart often implies a love that has gone wrong. Another theme might be pain and the process of healing from emotional distress.
The themes include the exploration of good and evil. The setting in the Congo makes the characters face their own morality. Racism is also a theme. The Europeans in the novel often look down on the African natives, which reflects the prevalent racist attitudes of that time. And there is the theme of isolation. Marlow is isolated during his journey, both physically in the African wilderness and psychologically from the people around him, which makes him question his own values.
The themes in 'The Heart of the Matter' include the struggle with self - deception. The characters deceive themselves about their motives and actions. Also, the theme of love and betrayal is prominent as relationships are tested throughout the novel.
