Seo In Guk admitted that he received a lot of stress playing Lee Hyun's character in 'I Remember You', confessing, "I was so stressed [playing Lee Hyun]. I don't dare say it was because I was crazy absorbed in my role, but because my understanding of the character got deeper. Though it was difficult going back and forth between my actual self and my actor self, the catharsis was twice as great."
On the atmosphere of the film set, Seo In Guk explained, "The director has a fun personality even though he has done a lot of hard works in the past. His relationship with the actor and actresses were good too. Jang Na Ra is also not the type who is too serious, so I got along well with her."
When inquired about his album plans, Seo In Guk replied, "It's because you only see me acting, but I'm always doing music. I've been taking guitar lessons, composing, and writing lyrics. I may focus more on my acting, but music is something that is more intimately connected to my everyday life. I haven't made any concrete plans, but now I want to try producing [my own music]," expressing his passion for both music and acting.
