His Only Color

To the rest of the world, brilliant tech CEO Jennie Kim is a cold, untouchable billionaire who lives his life in absolute monochrome.
But to Roseanne Park, the vibrant fashion stylist who grew up next door, he is simply the fiercely guarded boy who captured her heart.
After a tragic childhood accident stole his ability to see color, she became his only source of light, bringing warmth and beauty to his darkest days.
In return, he secretly built an empire from nothing just to provide her with an unshakeable, fiercely protective sanctuary.
Together, they seamlessly conceal each other's flaws, sharing a beautiful, intimate romance where she is his only color, and he is her ultimate safe haven.
