Eun-Soo is forced to go on a blind date with a 60-year-old loan shark to finance her adoptive father's presidential campaign. However, the person who shows up for the blind date is not the old man, but his grandson, Un-Ho. Un-Ho is Eun-Soo's unforgettable first love, but to Un-Ho, Eun-Soo is just the daughter of his enemy...

At that moment when love and hate intersect, dangerous emotional sparks begin to bloom.
