K-Drama 
Han I Ju, a painter adopted by Han Jin Ung and Lee Jeong Hye, has always been neglected by her family, including her younger sister, Han Yu Ra. Married to Yoo Se Hyeok, I Ju discovers he loves her sister instead. After a car accident, she wakes up in the past, before her engagement to Yoo Se Hyeok. Determined to change her fate, she breaks off the engagement and proposes a contract marriage to Seo Do Guk, the handsome grandson of the Taeja Group’s founder. He agrees, but hopes for it to become a real marriage
Both have:
A Cold CEO Male lead with TRAUMA.
(Hyde,Jekyll & I: Multiple Identitues Disorder.
Positively Yours: Post-traumatic Stress Disorder + ML self-blame for traumatic death of his brother)
And a more Warm Career Woman in a Romance with them.
The vibes of the dramas are similar too, since Positively Yours is like a callback to that era/Nostalgic 2016 style of kdrama.
