Adrian Cole
Age: 21 at the beginning / 26 after the time jump
The infamous bad boy of Westbridge University.
Adrian comes from a wealthy family and has always had everything money can buy.
He is confident, sarcastic, reckless, charming, and ridiculously popular.
Girls chase him.
Guys want to be him.
Professors consider him trouble.
His friends consider him the life of every party.
But beneath the arrogance is a young man who never learned how to express genuine feelings.
The bet begins as a joke.
Elena is supposed to be another temporary conquest.
Instead, she becomes the first person who makes Adrian want to become a better man.
When she leaves, he realizes too late that the game became real.
Five years later, Adrian is successful, mature, and far less reckless.
But he has never truly moved on.
When Elena returns, Adrian decides that this time he will earn her trust instead of demanding her forgiveness.
Elena Bennett
Age: 20 at the beginning / 25 after the time jump
The quiet nerdy girl of Westbridge University.
Elena loves books, academics, coffee, and peaceful corners where nobody bothers her.
She is intelligent, hardworking, kind, and emotionally guarded.
She doesn't trust easily.
Which makes falling for Adrian even more dangerous.
At first, she believes he's only interested in teasing her.
But Adrian slowly becomes the person she looks forward to seeing.
He makes her laugh.
He makes her feel beautiful.
He makes her believe that perhaps she can be loved exactly as she is.
Then she discovers the bet.
Her heart breaks.
After leaving the city, Elena raises her daughter alone while building a successful career.
Five years later, she no longer needs Adrian.
But seeing him again awakens feelings she thought she had buried forever.
Lily Bennett
Age: 4
Elena's adorable daughter.
Smart, curious, outspoken, and occasionally mischievous.
Lily has inherited Elena's intelligence and Adrian's stubborn personality.
She doesn't know Adrian is her father.
She simply thinks he's the strange man who keeps appearing around her mother.
And for some reason...
she likes him immediately.
Ethan Brooks
Adrian's best friend.
The person who originally starts the bet.
Ethan is arrogant, funny, and constantly looking for entertainment.
He never expects the harmless challenge to destroy Adrian's relationship with the only woman he has ever loved.
Years later, Ethan carries enormous guilt over what happened.
Mason Reed
Another member of Adrian's friend group.
More mature than Ethan and the first person to realize Adrian's feelings for Elena are genuine.
He tries to convince Adrian to end the bet before Elena discovers it.
Unfortunately, Adrian waits too long.
Sophia Carter
Elena's best friend.
Protective, sarcastic, and fiercely loyal.
Sophia knows how badly Elena was hurt and refuses to let Adrian walk back into her life without consequences.
She becomes Elena's biggest support during the five-year separation.
