Through '구가의 서', Lee Seung Gi gained further progress
~ Compared to modern dramas, there are many essential factors to take note of in sageuks, for example, way of expression, low or raised tone and dressing. Lee Seung Gi expressed, "During the filming of a sageuk, a long time is required to prepare the clothing and manner of dressing. And my body felt stressed because I wasn't able to sleep at home. The conveying of emotions is also stronger compared to modern dramas. Although filming was tiring, but it would be beneficial in the future. He added, "During the filming process, the most difficult part was the tone. For me who's familiar with modern dramas, it was hard to catch the sageuk's exact tone intensity. If I deliberately tried to emulate it, it turned to be even more awkward. Hence, after discussions with the director, we've decided to adjust and prioritise, correcting it gradually. The emotions in the eyes and expressions were in accordance to the script, conveying the emotions naturally.
Compared to good looks, Lee Seung Gi places more emphasis on character
~ When questions of dating were asked, Lee Seung Gi expressed, "Wanting to date has always been on my mind. (laughs)". As for his ideal type, he mentioned, "In the past, the criteria of my ideal type changed every 2 years. I think everyone goes through a period where we place emphasis on looks, I'm no exception. But I've changed now. I used to stubbornly prefer pretty girls, but I've changed a lot now. I like girls who make people around her comfortable, someone who is radiant and has a bright personality. Before, I thought that it's all right if she's older than me by 10 years, but I think it's a little unsuitable now. An appropriate age gap is okay.".
