If I hadn't read the webtoon, I wouldn't have even considered watching this drama. Not familiar with the female ML and the male ML always plays the same type of roles. The story doesn't follow the webtoon at all. Not only are things in different order, but they changed a lot. For example, the secretary also went back in time and died on the same day as the MLs, but that was never mentioned. Furthermore, his dad actually died...The webtoon also doesn't mention anything about art forgeries.
I liked Ji Hee (Yura) in Penthouse and in older dramas where she had child roles, but she's just not suitable for the character of Yura. The high heels don't make her look older and her character just feels forced.

I'm really not sure how this drama has such a high rating...not recommended.
