Adopted Affair - Park Sunghoon

Raised as sibling. Forced to fake love. Bound to cross the line.
Sofia was adopted into the wealthy Park family after a tragic accident took their daughter's life. Growing up, she constantly clashed with her aloof, deadpan brother Sunghoon, never close, always bickering. Years later, a scandal forces them into a fake marriage to protect the family's name.

Sofia, bold and boyish but kind at heart, brings chaos and warmth into Sunghoon's cold, calculated world. He's distant, sarcastic, and impossible to read, yet somehow always ends up cleaning up her messes. Living together, pretending to be a loving couple, their battles turn into something softer... but neither of them is ready to admit it.
