A career-focused Alpha heroine and a proud, prickly Omega heroine
The Omega heroine is a former child star and award-winning actress. Since childhood, she's had a crush on her childhood friend and neighbor, an Alpha boy she calls big brother. But she's so proud and awkward that he never notices. They rarely see each other once she starts filming, then go to different cities for college. Eventually, she watches him get engaged and married, and her brief, unrequited crush comes to an end. Then one day, she sees the Alpha heroine. The way she looks from behind reminds her of her neighbor, the Alpha boy, back in high school.
The Alpha heroine looks like a well-behaved, handsome high school boy from a distance. Her fair, gentle face resembles the popular pretty-boy Omegas. Admiring her and falling for her, she willingly lets the rich Omega keep her. But when she realizes she's just a stand-in, she decisively gets over it and focuses on her career.
