The Color of Her Heart (English Ver.)

Since her debut in 2014, Lee Sung Kyung has proven herself to be one of Korea's shining actresses, her achievements and performances never failing to leave a mark. Yet behind the brilliance of her career lies a part of her life she rarely allows the public to see-a past intertwined with Nam Joo Hyuk, her close friend who became a lover through a fleeting on-set romance, and ultimately, a wound she never expected to carry.

That story left a scar deeper than anyone realized. It wasn't just the heartbreak of losing someone she once loved; it was the devastating loss of a best friend. The pain taught her a brutal lesson, leading her to make a quiet vow: never again would she fall for a friend, a colleague, or anyone who stood too close. She built walls around her heart-high, steady, unyielding-and for years, those walls kept her safe.

Time passed. Slowly. Quietly.
Until 2023 arrived... bringing with it an encounter she never saw coming.

Fate placed her once more in the orbit of Kim Young Kwang, a long-time friend she hadn't seen in nearly a decade. Cast together in a romance drama that was impossible to refuse, Sung Kyung believed she could handle it with pure professionalism-nothing more, nothing less.

But reality had other plans.
Something inside her began to shift.

A small tremor-subtle, familiar-echoing through a heart she thought she had locked away for good.

Can she restrain the feelings she fears most?
Or is this the moment she must finally face the past she's been running from...
and allow herself to fall in love once more?
