It's a bit strange they decided to take that route for the ending. The last 24 episodes were the worst part about the drama, that portion was useless and it dragged forever. It should have ended after Shi Woo got out of the hospital by few episodes. Seo Hyo Rim had the least amount of screen-time during the last 24 episodes too, might be a reason for the direction it took.

The drama itself is a generic melodrama in a business setting and all the business related shenanigans. The cast performance can be a big hit or miss depending on the scene. Both male leads were too stiff most of the time. Nothing stands out about the story, birth secret, rich/poor, in-laws ....etc, you know how it goes, prolonging everything to fill the time slot. Can't recommend it unless you're into these kind of long-running lower-budget type of melodramas, then you'll be able to tolerate it.
