There could be social consequences too. In many novels, the characters live in a community or social circle. When the cheating is discovered, the person who cheated and the best friend might be ostracized. Their reputations can be severely damaged, and they may face a lot of judgment from others. It can also lead to a cycle of guilt and self - loathing for the ones who were involved in the cheating.
Growth and self - discovery are also common themes. Through the process of realizing their feelings for their best friend, the characters often learn more about themselves. They might discover new aspects of their personality, like their capacity for deep emotional connection or their insecurities when it comes to love. This can be seen in novels where the main character changes and matures as they navigate their feelings for their best friend.

They had already built a strong foundation of trust as friends, which easily transferred into a romantic relationship. Also, there's often a turning point. It could be a difficult situation like an illness or a special event like a trip that makes them see their relationship in a new way.
