One of the main themes could be the complexity of relationships. Love often involves various emotions and power dynamics, and lies can be a part of that complexity. Fiction might be used to explore these themes in different scenarios, perhaps showing how characters create false personas or stories within the context of love.
It's likely that there are some secondary characters as well. These could be friends or family members of the main characters. They might play important roles in either perpetuating the lies or trying to expose them. For instance, a best friend of one of the main characters might suspect that their friend is lying about their relationship and try to get to the bottom of it. Or a family member could be the one who starts the cycle of lies for some reason related to family honor or protection.
Betrayal is a common theme. In these novels, characters often betray their partners through lies, like hiding an affair or false feelings. For instance, in a typical 'lies of love novel', a character might say they love someone while actually being interested in someone else's money or status.
The theme of forgiveness is also prevalent. When the lies are revealed, the love between the characters has to be strong enough to overcome the betrayal. In many fanfictions, this involves a period of estrangement followed by a heartfelt reconciliation where the characters realize that the love is more important than the lies.
In 'Big Little Lies Novel', the theme of social status is prominent. The characters are very much aware of their social standing in the community and how their actions and secrets could impact it. And secrecy is also a big theme as the characters try to keep various aspects of their lives hidden from others.
The main themes would likely be deception and love. Deception because of the 'web of lies' part, and love as it starts with 'love at first text'.
