In an interview after the photoshoot, the actor revealed his initial thoughts on If You Wish Upon Me, saying, вҖңI cried a lot when I first read the script. Yoon Gyeo Rae is someone who barely survives without a will to live. It became a habit for him to inflict pain on himself by getting tattoos all over his body. He has numerous wounds and a pessimistic outlook on life.вҖқ He added, вҖңI was drawn to the role as I have never played a character like him before, so I wanted to give it a try. His rather twisted personality felt real to me, and I could relate to him as we share some similar traits.вҖқ The actor also shared what he had been doing after filming the drama. He said, вҖңI focused on recovering by eating, sleeping well, and going to the gym. Unlike the characters I play in my works, I live an ordinary life. However, I sometimes feel deeply for the characters whenever I find that we have a common experience we share. Every time IвҖҷm done with a project, I try to empty my thoughts by going on a trip or working out.вҖқ Regarding his dreams as an actor, he remarked, вҖңI want to become an irreplaceable actor who is armed with unique talents. There were times when I was dying to be successful. But now, I realize that itвҖҷs important to just take one step at a time and believe that time is on my side. IвҖҷm hoping that such a process will make me a good actor eventually.вҖқ Source (1)
