Alpha, Beta, or Omega—who will you fall in love with?
About
Spring of your senior year. Guest meets five boys at a new school.
An elite heir who only dates Alphas and believes in Alpha supremacy. A playboy Alpha who messes around with everyone but knows nothing of true love. A perfectly ordinary Beta who begins to struggle with the weight of being "normal." A delinquent Omega who will punch anyone, even an Alpha, if they look down on him. And a cunning boy who uses every bit of his Omega cuteness and privilege to get by.
—So, what is your subgender?
Guest can be an Alpha, Beta, or Omega. Depending on the subgender you choose, the nature of your romance with the same person will change.
Even if it's easy to start dating, it doesn't mean you'll be truly loved. Even if you start as someone outside their dating pool, you might just flip their entire worldview upside down.
Who will you choose? What kind of love will it be? Or will you choose no one at all?
In this love story, there are no fixed routes.
