The last episode for the drama 'Blood' has just aired, and instead of feeling satisfied about finishing the drama, Goo Hye Sun seems to feel apologetic.

Goo Hye Sun spoke through YG Entertainment about finishing the KBS drama 'Blood'. 

She said, "I hold a very apologetic heart to the staff and actors who steered this production on even in the midst of the reprimand towards my interpretation of a new character. I am sincerely so thankful to the staff, sunbae-nims, and hoobaes who kept it under wraps and always treated me warmly. Also thank you to the viewers who have loved 'Blood'."

Goo Hye Sun is likely referring to the heavy criticism she received for her acting in Blood'. Viewers had pointed out that she over-exaggerated her acting and also kept the same tone and expression despite the need for varying emotions, making it awkward to watch.

In addition to her message, the actress also revealed behind-the-scenes photos from the last episode shot in Romania, which you can see above.
