Perhaps there is a female character who serves as a muse or a love interest for the main character.

Since we only have the title 'love lust and life novel', it's difficult to say exactly who the main characters are. It might be a group of friends. One friend could be more driven by love, always looking for deep emotional connections. Another might be more influenced by lust, being more impulsive in relationships. And they all are dealing with the ups and downs of life together.
It might be a group of friends who support each other in their quests for a more fulfilling life. They each have their own dreams and challenges, but together they inspire a lust for life in one another.
