In a college world where every hallway is a battlefield of intellect, pride, and desire, Rival Hearts explores the thin line between hate and a love that burns hotter than anyone expects. When fiercely independent Harper Lawson, a chemistry major with a sharp tongue and a stubborn streak, collides with Emery Collins, a confident and ambitious literature student, sparks fly—literally. Their rivalry begins in classrooms and spills into dorms, cafeterias, and late-night campus corners. Harper thrives on rules and routine, while Emery lives for unpredictability and teasing chaos.

As the semester unfolds, Harper and Emery navigate parties, group projects, dorm-room secrets, and the intoxicating highs of desire and intimacy. Amid campus gossip, emotional upheavals, and raw, steamy encounters, Rival Hearts captures the journey of two women learning that love can come disguised as hate, that surrendering to desire can be terrifyingly exhilarating, and that the fiercest rivals often make the strongest partners. Full of witty banter, heart-pounding tension, and intimate romance, this novel is a slow-burning, passionate exploration of the chaos of first love and the unstoppable force of attraction.

Everyone in the company knows one thing about Ethan Jang. Our CEO has no heart. Cold. Emotionless. Brutal enough to fire someone before they finish “Good morning.” So imagine my shock when I walk into his office at 2 a.m. and catch the “Ice King of Seoul” ugly-crying over a K-drama, clutching a tissue and whispering, “Don’t die, Eun-bi… please…” I should’ve backed out slowly. Instead, he saw me. Now Ethan Jang billionaire, perfectionist, professional soul-crusher — is doing everything to shut me up: bribing me with bonuses, threatening to transfer me to Antarctica, and begging me (yes, begging) to keep his midnight K-drama breakdowns a secret. But hiding it becomes impossible when: • He accidentally quotes K-drama love lines during meetings. • He drags me into a fake-dating scandal to protect his image. • He insists on “rehearsing” romantic confession scenes with me… too close, too intensely. • And worst of all, his cold façade starts cracking — and I’m starting to like what I see underneath. He’s all logic and walls. I’m chaos, emotions, and bad decisions. We were never meant to mix… yet somehow we’re falling into the messiest, funniest, and most unexpected romance of our lives. Because the scariest man in the company isn’t heartless after all he’s just been waiting for someone to rewrite his script.
