Goo Hye Sun even got the help of a staff member to use their cellphone as a light, so that she can read her script in the dark and put her script on top of her head, unable to part with it. Goo Hye Sun's forte is dramatic acting, and she has been touching viewers' hearts with how in tune she is with her character's emotions on 'Angel Eyes'.

The drama's rep stated, "Goo Hye Sun has perfected her character Yoon Soo Wan by understanding what Dong Joo means to her and how precious their first love is deep inside her heart... She has a lot of affection for the production, and as much as she is channeling her character daily, it would definitely be good to anticipate her future activities."
