The female lead is a doctor and I believe she specialises in heart surgery (this is what i remember as i read it months ago) and she is the head of her department at the hospital. I think she’s a cardiothoracic surgeon. The hospital was acquired by another company which the male lead is the successor of. Also, the male lead becomes the new ceo of the hospital.
This is all I remember, please help if you know the name of this webtoon, I read it on the TAPAS APP.
