But Quan exceeds her expectations with his supportive, sweet nature.

When she comes across Quan’s profile on a dating app, she thinks he seems like a fun fling. He’s surprised when she agrees, and even more surprised when Anna is actually motivated to find another partner for herself. What’s more, her longtime boyfriend proposes an open relationship instead of marriage. But now she’s burned out creatively and emotionally, much to the dismay of her ambitious parents.

That match is Anna Sun, a violinist who recently went viral online and skyrocketed to success. It’s finally time for charming, fashionable, motorcycle-riding Quan Diep to meet his match. The Heart Principle is easily one of the year’s most anticipated romances, as it stars a character who’s been a fan favorite ever since Helen Hoang’s 2018 debut, The Kiss Quotient.
